2 STEP-DOWN DC/DC 2 XC9267/68 36V.6A Synchronous Step-Down DC/DC Converter The XC9267/68 is a synchronous step-down DC/ DC with P-Ch High Side Switch to ensure low voltage operation with 1% max duty ratio. It can operate from 3.V~36.V and deliver loads up to 6mA making it an ideal replacement for inefficient Linear Regulators used in many industrial applications. Designed for very high efficiencies at low output loads, with low quiescent current and automatic PFM/ mode. The XC9267/68 also works with Low ESR ceramic capacitors and comes with a choice of two switching frequencies, adjustable soft start and a power good output. Available in the ultra-small USP-6C package, measuring only 2. x 1.8 x.6mm an extremely small DC/DC circuit can be implemented with a minimal number of external components. The XC9267/68 includes a fold-back type current limit circuit and the IC will automatically resume normal operation as soon as the over-current condition disappears.

3 3 FOLD-BACK TYPE LIMIT PROTECTION The current limiting circuit has both High Side Switch Current Limit and Low Side Switch Current Limit. These two current limits realise the fold-back current limiting operation and the Oscillation Frequency goes down automatically under current limit situation. A Inductor Current reaches to the High Side Current Limit When inductor current reaches to the High Side current limit (ILMH), the Low Side switch is kept on until the current reached to the Low Side current limit (ILML). It makes the oscillation frequency lower. B Fold-back Operation When V OUT (FB) voltage falls down with the current limit operation, ILMH and ILML values go down also for the fold-back operation. C Automatic Restart When the load becomes lighter, V OUT rises up automatically without inrush current along with the fold-back current limit rising. I LIMH =1.5A (typ) I LIML =.75A (typ) ILX A VOUT VLX VOUT V STABLE OPERATION FROM LOWER INPUT S Many traditional mid-voltage DC/DC converters use an Nch MOSFET for the High Side switch. Whilst an Nch FET is excellent for high speed switching it normally needs a special bootstrap circuit to drive it. A bootstrap circuit has the advantage of being simple and low cost, but it also has limitations. The Duty-cycle and on time is limited by the requirement to refresh the charge in the bootstrap capacitor, which means the maximum duty ratio can never be 1% and this has implications when the input Voltage goes below VOUT as shown in the diagram below. The XC9267/68 uses a Pch MOSFET for the High Side Switch that does not need a bootstrap circuit, so the maximum duty ratio can be 1%. This means that the output remains stable even when the input drops beneath VOUT as shown in the diagram below: The XC9267/68 output follows the input when it goes below VOUT and this can be important for automotive cold crank applications or for when the VIN source has a high impedance (for example from a long cable).

4 STEP-DOWN DC/DC 4 XC V 3A Hi-SAT COT Step-Down DC/DC Converter The XC9273 incorporates Hi-SAT COT, Torex s own Constant On-Time architecture, to deliver extremely fast transient response performance and high efficiency. With Hi-SAT the XC9273 only needs one low cost 47μF ceramic capacitor at the output side, whilst competitors often need multiple capacitors to achieve similar levels of performance. However adding an extra capacitor will allow the user to reduce output ripple further if required. Hi-SAT COT also provides less fluctuation in oscillation frequency against load and input voltage when compared to traditional COT control architectures. With a.6v reference voltage source the output voltage can be set freely from.8v using external resistors. Furthermore, it is possible to control the output voltage dynamically using an external digital-to-analog converter (DAC). The XC9273 also allows the engineer to select different features using the MODE pins. Using a High or Low signal the engineer can select control or auto switching control (MODE1), Short Protection with latch or hiccup mode (MODE2) and optional CL discharge with soft OFF (MODE3). The integral soft start time can be adjusted with an external capacitor (CSS) and a Power Good feature is also included to help with system power-up sequencing.

Many of the features are still available, but the parameters are set at the factory and users select their preferences through the part number ordered. This reduces the number of pins needed and the XC9274/75 is available in SOP-8FD measuring 6.mm x 4.9mm x 1.55mm and the package incorporates an exposed GND tab to maximise heat dissipation.

6 STEP-DOWN DC/DC 6 XC9272 Low Voltage, Ultra Low Power Synchronous Step-Down DC/DC The XC9272 series of DC/DC converters supports lower output voltages from.6v to.95v, and achieves an ultra-low supply current of.5μa. This enables power to be supplied with high-efficiency to chipsets that require a core voltage under 1.V and maximises the performance of low-voltage chipsets. Optimization of the analog circuitry to realise a supply current of.5μa and the use of PFM control for the operation method enable this product to achieve a significant increase of efficiency at light loads compared to conventional products. These characteristics make this power IC ideal for applications that require a long battery drive time, such as devices with a GPS function, wearable devices, energy harvesting and other devices in which efficiency in the sleep state is important. The XC9272 series also features an enable pin to turn the IC on and off and an optional CL discharge function that can quickly discharge the output capacitor when the IC is turned off. During stand-by, all circuits are shutdown to reduce consumption to less than.1μa.

7 7 BENEFITS OF OPERATING AT LOWER S FOR CHIPSET CORE SUPPLY It s well known than operating a microprocessor core at lower voltages will reduce overall power consumption, which in turn leads to less heat being produced and cooler devices can be made to run faster. So as designers look to improve battery life whilst also increasing levels of performance the trend is inevitably towards lower and lower chipset Voltages as can be seen in fig.1 to the right. 5.V 4.V 3.3V VDD Voltage VDD Voltage VDD Voltage Previously core voltages operated between 1.8V and 1.1V but increasingly voltages below 1.V are becoming popular for wearable devices and energy harvesting applications 1.8V 1.V Core Voltage Core Voltage.6V ~ 2 25 ~ ~ Fig.1 The evolution of chipset operating voltages The new XC9272 combines small size, highefficiency and the ability to supply a low voltage under 1V with high accuracy and this enables the engineer to significantly extend battery life. To explore this further, we compare the performance under the following conditions at different output voltages. Test Condition V IN = 3.6V Operating Modes Active: IOUT = 1mA for 1ms Sleep: IOUT = 1μA for 5s First, we tested a standard DC/DC with an IQ of 15μA and used it to generate 1.8V which is the typical core voltage required for many of today s microprocessor cores. We then used the same DC/DC to generate.7v under the same conditions and finally we used the new XC9272 in the same circuit to generate.7v. All three tests used the active and sleep modes indicted above and in fig.2 and fig.3 you can see the results. Using the XC9272 to drive a.7v core voltage dramatically reduced overall power consumption and subsequently increased the system battery life almost 5 times.

8 LI-ION / LI-PO BATTERY CHARGERS 8 XC686 Li-Ion / Li-Polymer Battery Charger with Temperature Monitoring, Current Path & Shutdown The XC686 is a linear Li-Ion/Li-Po battery charger with a 45mA Input Current Limit and integrated Current Path to maintain and prioritise the system load during the charging cycle. It also includes a novel Storage Mode Shutdown function to help conserve battery life whilst the end product is in transit to the shops. The integral input current limit makes the XC686 ideal for USB charging or applications that use smaller AC/DC adaptors. The temperature monitoring function meets JEITA standards and by controlling the charge voltage and charge current as appropriate for the temperature, the battery can be charged safely. Additional protective functions include a safety timer, UVLO, thermal control, and reverse current protection. The Storage Mode Shutdown function completely shuts off power supply from the battery to the system to prevent battery leakage current while the device is in storage. When a power is connected to V IN the Shutdown Mode is cleared. This allows the device to be operated with full battery immediately after purchase even if it has been in storage for extended periods of time. The XC686 is available in the small USP-1B or LGA-1B1 package and a charging circuit can be designed with minimal external components.

During this time, to avoid the battery discharging, the Li-ion / Li-Po cell should ideally be disconnected from the system. This is not always possible with traditional Charging IC, but the XC686 includes an additional Charge Switch to allow the user to cut-off the connection between battery and the System The connection is cut using the integral diode of the Charge SW. A toggle signal to the SD pin enables the Shutdown mode operation when there is no VIN and once enabled, the consumption current from the BAT pin is only.1μa.

9 9 XC686: OPERATION OF PATH FUNCTION Example: CC = 38mA case 5mA 45mA I OUT A I OUT for the system is ma, so, both IIN and the charge current (I BAT ) are 38mA. 7mA ma 45mA 38mA B When the system uses to 7mA, I BAT is kept as 38mA and I IN increases 38mA to 45mA. I VIN ma C When the system needs more current, the charge current (I BAT ) decreases to fit to the input current limit: 45mA as total. 38mA I BAT ma -5mA D When the system requires higher current larger than the input current limit: 45mA, the battery supports the gap, therefore I BAT value goes to minus.

This shortens the path of the switching current and minimises noise. Lowest cost as very standard coil can be used. Special wire bonding for ultra-low profile. The IC and coil have good heat dissipation, so large currents can be used. New construction for mid-voltage products Low EMI / Radiated Noise Another benefit for Torex MICRO DC/DC is much lower radiated noise compared with a normal DC/DC IC with an external coil. The data below compares the EMI performance and magnetic field strength for the different packaging options. When the IC is embedded under the Coil we see the lowest emissions (XCL22 type), but all MICRO DC/DC generate considerably less radiated noise compared to the traditional topology (XC9261 type): MICRO DC/DC UNBEATABLE EMI PERFORMANCE XC9261B18DER-G (F OSC =3.MHz, Hi-SAT COT) XCL214B183DR (F OSC =3.MHz, Hi-SAT COT) XCL22B183FR-G (F OSC =3.MHz Hi-SAT COT) 7 6 VCCI Class B(QP) Horizontial(Peak) 7 6 VCCI Class B(QP) Horizontial(Peak) 7 6 VCCI Class B(QP) Horizontial(Peak) EMI PERFORMANCE Horizontal Level [dbuv/m] 5 4 VCCI Class B[1m] Frequency [MHz] 7 VCCI Class B(QP) 6 Vertical(Peak) Horizontal Level [dbuv/m] 5 4 VCCI Class B[1m] Frequency [MHz] 7 VCCI Class B(QP) 6 Vertical(Peak) Horizontal Level [dbuv/m] 5 4 VCCI Class B[1m] Frequency [MHz] 7 VCCI Class B(QP) 6 Vertical(Peak) Vertical Level [dbuv/m] Vertical Vertical CONSTRUCTION VCCI Class B[1m] Level [dbuv/m] VCCI Class B[1m] Level [dbuv/m] VCCI Class B[1m] Frequency [MHz] Frequency [MHz] Frequency [MHz]

11 XCL223/24 Low Profile, Step-Down, Micro DC/DC Converter with Integrated Coil 11 The XCL223/24 is a family of Ultra Low Profile Micro DC/DC Step-Down Converters with integrated coil. Measuring only 2.25mm x 1.5mm x.75mm (max), the XCL223/24 series is designed to minimise EMI emissions and maximize efficiency, while delivering a very stable output with low peak to peak ripple Voltage (<1mV). Utilising Hi-SAT COT, Torex s Constant ON Time architecture gives the XCL223/24 extremely fast load transient response performance in comparison to standard DC/DC solutions. Hi- SAT COT also provides less fluctuation in oscillation frequency against load and input voltage when compared to traditional COT control architectures. The small size and simple circuit architecture makes the XCL223/24 an ideal replacement for inefficient LDO voltage regulators and by integrating the coil, Torex has simplified the circuit layout for the designer and reduced the number of external components normally needed to implement this type of DC/DC solution. The smaller circuit layout also means less PCB tracking, which helps further reduce the radiated noise. 4mA (B Type) Output Current 7mA (A Type) N-Ch.1 (typ) ON Resistance P-Ch.14 (typ) Input Voltage Range 2.7V ~ 5.5V Output Voltage Range.8V ~ 3.6V Switching Frequency 3.MHz Quiescent Current 25μA (typ) Max Duty Cycle 1% XCL223 Fixed Control Product Select XCL224 Automatic Switching Current Limit Circuit Thermal Shut Down Protection Circuits Short Circuit Protection ULVO (2.V) World s Smallest Micro DC/DC 2.25 x 1.5 x.75mm Additional Features Package High Speed Soft-start CL Discharge Low ESR Ceramic capacitors USP-8B1 INTERNAL CONSTRUCTION TOP View Inductor L2 L1 CE Lx V OUT AGND C L 1μF C IN 4.7μF V IN PGND DC/DC Package EFFICIENCY VS.

A stable and efficient power supply circuit can be configured by simply adding only two ceramic capacitors externally thereby contributing to PCB space saving and the shortening of development time. Integration of the coil simplifies the board layout and minimises any unwanted radiated noise. With a P-Ch High Side Switch to ensure low Voltage operation and 1% max duty ratio, the XCL225/26 can operate from 3.V~18.V and deliver loads up to 5mA. It s designed for very high efficiencies at low output loads, with low quiescent current and automatic PFM/ mode.

13 XCL12/3 5.5V Step-Up Micro DC/DC Converter with Integrated Coil 13 The XCL12/3 series is a synchronous boost converter with integrated coil that is optimised to provide high efficiencies under all load conditions. The DC/DC circuit integrates a.3 Nch driver transistor and a.3 synchronous Pch switching transistor. The internal switching frequency is 3.MHz and output currents up to 5mA can be realised with only two low cost ceramic capacitors. The internal circuit can start operation from Input voltages as low as.85v and once started will continue to operate until the input goes below.65v. The output voltage is set internally between 2.2V~5.5V (±2%) in.1v increments and with a quiescent current of only 26μA reducing to.1μa during standby, the XCL12/3 helps to further maximise battery life in portable applications. This series also features an optional load disconnect function that prevents the battery charge from leaking to the output while the IC is not operating or an Input bypass mode function to keep the connection between the input and output side during shutdown.

14 LDO REGULATORS 14 XC651 2mA High Speed LDO in an Ultra Low Profile Package This low noise CMOS LDO regulator can provide a stable output voltage without needing an external load capacitor (C L ) because unlike other LDO the phase compensation is carried out internally, on chip. The CE function enables the circuit to be put into stand-by mode by inputting a low level signal to the CE pin thereby reducing current consumption from an already low 13μA (in operation) to less than.1μa. The current limit fold-back circuit operates as a short circuit protection and a current limiter function for the output pin. The XC651 is now available in the new tiny, ultra-low profile WLP-4-1 package. It is one of the thinnest on the market, making it ideal for smart card and wearable applications.

15 XC623 2A High Speed LDO with Reverse Current Protection 15 The XC623 is a small and fast multifunction LDO regulator with a maximum output current of 2A and an adjustable output voltage and current limit value. An internal.17 low ON resistance P-ch Tr. and a stable output voltage with small dropout voltage make these products ideal for post regulators (DC/DC rear-stage ripple removal), various types of microcontrollers, regulators for logic applications, and secondary power supplies. The XC623 series can also be used in consumer electronics, industrial equipment, communication modules, and electricity smart meters. In addition to a function that enables the output voltage and current limit value to be set externally and a function that prevents a reverse current higher than the input pin (VIN) from flowing into the output pin (VOUT), a rich variety of protective circuits such as overheating protection (TSD) and startup rush current prevention can be added. Output Current 2.A Adjustable Current Limit.3A ~ 2.5A On 3.3V / 1A Dropout 3.3V / 1A Input Voltage 1.7V ~ 6.V Output Voltage 1.2V ~ 5.V Quiescent Current 45μA Reverse Current Protection YES Inrush Current Prevention YES CL High Speed Discharge YES Thermal shutdown YES Op. Ambient Temperature -4 C ~ +15 C The output voltage and over-current limit value can be set using a total of only five chip capacitors and chip resistors.
