This is the most "low-voltage" current available from a standard 1" x " package, and these power converters exemplify Murata Power Solutions relentless drive to bring you more power/current, from standard packages, without compromising reliability or resorting to thermal specmanship. By combining a high-frequency, high-efficiency (to 88%), synchronous-rectifier topology with the newest components and time-tested, fully automated, SMT-on-pcb construction, these are able to bring you 7-15W (@ up to A) in the standard 1" x " package from which most competitors can only get 5-10W (@ -A). All UWR s deliver their full output power over ambient temperature ranges from 0 C to as high as + C (model and input voltage dependent) without heat sinks or supplemental forced-air cooling. Devices derate to +100 C. Output voltages are 1., 1.5, 1.8,.5,., 5, 1 or 15 Volts. Input voltage ranges are 10-18V (D1 models), 18-V (D models) or -V (D8 models). All models feature input pi filters, input undervoltage and overvoltage lockout, input reverse-polarity protection, output overvoltage protection, output current limiting, and continuous short-circuit protection. On/off control and outputtrim functions are optional (see Optional Functions). All models are designed to meet IEC9, UL19 and EN9-1, nd Edition safety requirements. D8 models (-V inputs) are CE marked. UWR 7-15W DC/DC s are packaged in lowcost, light-weight, diallyl phthalate (UL9V-0 rated) plastic packages with standoffs. EMC compliance is achieved via a low-noise design rather than through expensive metal shielding. +VIN (1) +VOUT () SWITCH CONTROL COMMON () VIN () ON/OFF CONTROL () (OPTIONAL) UVLO & OVLO COMPARATORS PWM CONTROLLER OPTO ISOLATION REFERENCE & ERROR AMP Typical topology is shown.

4 Floating Outputs Since these are isolated DC/DC converters, their outputs are "floating." Designers will usually use the output Common (pin ) as the ground/return of the load circuit. You can, however, use the +Output (pin ) as ground/return to effectively reverse the output polarity. Minimum Output Loading Requirements 1. to 5V models employ a synchronous-rectifier design topology. All models regulate within spec and are stable under no-load conditions. 1/15V models employ a traditional forward architecture and require 10% loading (15mA for 1V models, 100mA for 15V models) to achieve their listed regulation specs. 1/15V models also have a minimum-load-for-stability requirement (0mA). For 1/15V models, operation below 0mA or 10% loading will be stable but regulation may degrade. A 100µF output capacitor is recommended below 10% loading. Users should verify whether this relaxed regulation will have any effect on output circuits. If so, add a small load of 10% or greater. Operation under no-load conditions will not damage 1/15V converters. However they may not meet all listed specifications. Filtering and Noise Reduction All A-Series UWR DC/DC Converters achieve their rated ripple and noise specifications using the external input and output capacitors specified in the Performance/Functional Specifications table. In critical applications, input/ output noise may be further reduced by installing additional external I/O caps. Input capacitors should be selected for bulk capacitance, low ESR and high rms-ripple-current ratings. Output capacitors should be selected for low ESR and appropriate frequency response. All caps should have appropriate voltage ratings and be mounted - inches from the converter to achieve published ratings. The most effective combination of external I/O capacitors will be a function of your particular load and layout conditions. Input Fusing Certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. Fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists. For MPS's A-Series UWR 7-15 Watt DC/DC Converters, you should use fast-blow type fuses with values no greater than the following. VIN Range "D1A" Models "DA" Models "D8A" Models Fuse Value Amps Amps 1 Amp Maximum Case Temperature The +100 degree C. maximum outside case temperature specification is based on much empirical testing on encapsulated units. Those tests show that if the case exterior can be maintained at or below +100C., the hottest internal components package temperatures will not exceed +18C. because of the internal temperature gradient to the exterior case. This latter +18C. internal figure is a safety margin offering more protection for the internal components. The +100C. case specification must be achieved by the user s combination of lower output current and/or higher airflow. If you attempt any of your own case temperature testing, please be aware of the heatsinking effect of attaching wired thermocouples to surfaces. An infra red camera is a another alternative which avoids the TC heatsinking effect. But the IR camera must be calibrated frequently and accurately. Remember too that it is quite difficult to accurately measure airflow right at the converter. Murata Power Solutions uses a calibrated wind tunnel with large amounts of data history. Because of thermal time constants, allow plenty of time for temperature stabilization. Trimming Output Voltages These converters have a trim capability (pin 5) that allows users to adjust the output voltage ±5%. Adjustments to the output voltage can be accomplished via a trim pot, Figure, or a single fixed resistor as shown in Figures and. A single fixed resistor can increase or decrease the output voltage depending on its connection. Fixed resistors should have an absolute TCR less than 100ppm/ C to minimize sensitivity to changes in temperature. A single resistor connected from the Trim (pin 5) to the +Output (pin ), see Figure, will decrease the output voltage. A resistor connected from the Trim (pin 5) to Output Common (pin ) will increase the output voltage. Trim adjustment greater than 5% can have an adverse effect on the converter's performance and is not recommended VIN VIN ON/OFF CONTROL +VIN VIN ON/OFF CONTROL +VIN VIN ON/OFF CONTROL +VOUT TRIM COMMON +VOUT TRIM COMMON +VOUT TRIM COMMON kΩ 5- Turns Figure.

Soldering Guidelines Murata Power Solutions recommends the specifications below when installing these converters. These specifications vary depending on the solder type. Exceeding these specifications may cause damage to the product. Be cautious when there is high atmospheric humidity. Your production environment may differ; therefore please thoroughly review these guidelines with your process engineers. Wave Solder Operations for through-hole mounted products (THMT) For Sn/Ag/Cu based solders: Maximum Preheat Temperature 115 C. Maximum Pot Temperature C. Maximum Solder Dwell Time 7 seconds For Sn/Pb based solders: Maximum Preheat Temperature 105 C. Maximum Pot Temperature C. Maximum Solder Dwell Time seconds Start-Up Threshold and Undervoltage Shutdown Under normal start-up conditions, devices will not begin to regulate until the ramping-up input voltage exceeds the Start-Up Threshold Voltage (5V for "D8A" models). Once operating, devices will not turn off until the input voltage drops below the Undervoltage Shutdown/Lockout limit (V for "D8A" models). Subsequent re-start will not occur until the input is brought back up to the Start-Up Threshold. This built-in hysteresis obviously avoids any indeterminate on/off situations at a single voltage. Start-Up Time The VIN to VOUT Start-Up Time is the interval between the time at which a ramping input voltage crosses the turn-on threshold point and the fully-loaded output voltage enters and remains within its specified accuracy band. Actual measured times will vary with input source impedance, external input capacitance, and the slew rate and final value of the input voltage as it appears to the converter. The On/Off to VOUT Start-Up Time assumes the converter is turned off via the On/Off Control with the nominal input voltage already applied to the converter. The specification defines the interval between the time at which the converter is turned on and the fully-loaded output voltage enters and remains within its specified accuracy band. Accuracy of adjustment is subject to tolerances or resistor values and factory-adjusted output accuracy. VO = desired output voltage. MDC_UWR_7-15.I0 Page 5 of 1

6 Temperature Derating Curves for UWR 7-15W A-Series The thermal performance of A-Series UWR 7-15 Watt DC/DC Converters is depicted in the derating curves shown below. All devices, when operated at full load, in still ambient air, over their full specified input voltage range, can safely operate to TA maximum. All models, other than the D1A models (10-18 Volt input range), can operate at higher ambient temperatures if the input range is narrowed. For example, model UWR-5/000-D8A can operate safely to + C if the input range is kept between and 8 Volts.
