Description The Q/QW030-Series Power Modules are dc-dc converters that operate over an input voltage range of 18 to 36 or 36 to 7 5 and provide a precisely regulated dc output. The outputs are fully isolated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings of 30 W at a typical full-load efficiency of up to 86%. These encapsulated modules offer a metal case for optimum thermal performance. Threaded-through holes are provided to allow easy mounting or addition of a heat sink for high-temperature applications. The standard feature set includes remote sensing, output trim, and remote on/off for convenient flexibility in distributed power applications.

This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow fuse with a maximum rating of 5 (for QW030) and 10 (for Q030) (see Safety onsiderations section). ased on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used.

7 Data Sheet pril 2002 Design onsiderations (continued) Input Source Impedance QW/Q030-Series Power Modules: dc-dc onverters; eature Descriptions Overcurrent Protection The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module. If the input source inductance exceeds 4 µh, a 33 µ electrolytic capacitor (ESR < 0.7 Ω at 100 khz) mounted close to the power module helps ensure stability of the unit. Safety onsiderations QW Modules or safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950, S 22.2 No , and DE 0805 (EN ). If the input source is non-sel (EL or a hazardous voltage greater than 60 and less than or equal to 75 ), for the module s output to be considered meeting the requirements of safety extra-low voltage (SEL), all of the following must be true: The input source is to be provided with reinforced insulation from any hazardous voltages, including the ac mains. One I pin and one O pin are to be grounded, or both the input and output pins are to be kept floating. The input pins of the module are not operator accessible. nother SEL reliability test is conducted on the whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module s output. Note: Do not ground either of the input pins of the module without grounding one of the output pins. This may allow a non-sel voltage to appear between the output pin and ground. The power module has extra-low voltage (EL) outputs when all inputs are EL. The input to the QW030 is to be provided with a maximum 5 normal-blow fuse in the ungrounded lead. The input to the Q030 is to be provided with a maximum 10 normal-blow fuse in the ungrounded lead. Tyco Electronics orp. To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry and can endure current limiting for an unlimited duration. t the point of current-limit inception, the unit shifts from voltage control to current control. If the output voltage is pulled very low during a severe fault, the current-limit circuit can exhibit either foldback or tailout characteristics (output-current decrease or increase). The unit operates normally once the output current is brought back into its specified range. Remote On/Off Two remote on/off options are available. Positive logic remote on/off turns the module on during a logic-high voltage on the remote ON/O pin, and off during a logic low. Negative logic remote on/off, device code suffix 1, turns the module off during logic-high voltage and on during a logic low. To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the I( ) terminal (on/off). The switch may be an open collector or equivalent (see igure 4). logic low is on/off = 0.7 to 1.2. The maximum Ion/off during a logic low is 1 m. The switch should maintain a logic-low voltage while sinking 1 m. During a logic high, the maximum on/off generated by the power module is 15. The maximum allowable leakage current of the switch at on/off = 15 is 50 µ. If not using the remote on/off feature, do one of the following: or positive logic, leave the ON/O pin open. or negative logic, short the ON/O pin to I( ). - on/off + Ion/off I(+) I(-) REMOTE ON/O igure 4.

8 QW/Q030-Series Power Modules: dc-dc onverters; Data Sheet pril 2002 eature Descriptions (continued) Remote Sense Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections. The voltage between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in the eature Specifications table, e.g., on the QW030: [O(+) O( )] [SENSE(+) SENSE( )] 0.5 The voltage between the O(+) and O( ) terminals must not exceed the minimum output overvoltage protection value shown in the eature Specifications table. This limit includes any increase in voltage due to remote-sense compensation and output voltage setpoint adjustment (trim). See igure 5. If not using the remote-sense feature to regulate the output at the point of load, then connect SENSE(+) to O(+) and SENSE( ) to O( ) at the module. lthough the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. onsult your Tyco Electronics ccount Manager or pplication Engineer if you need to increase the output voltage more than the above limitation. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. are should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power.

Q/QW030-Series Effective ircuit onfiguration for Single-Module Remote- Sense Operation LOD Output oltage Set-Point djustment (Trim) Output voltage trim allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the SENSE(+) or SENSE( ) pins. The trim resistor should be positioned close to the module. If not using the trim feature, leave the TRIM pin open. With an external resistor between the TRIM and SENSE(+) pins (Radj-down), the output voltage set point (O, adj) decreases (see igure 6). The following equation determines the required external-resistor value to obtain a change in output voltage from O, nom to O, adj. The values of G, H, and L are shown in Table 5. Radj-down = ( O, adj L)G ( O, nom O, adj) H Ω The Q/QW030 modules have a fixed current-limit set point. s the output voltage is adjusted down, the available output power is reduced. With an external resistor connected between the TRIM and SENSE( ) pins (Radj-up), the output voltage set point (O, adj) increases (see igure 7). The following equation determines the required external-resistor value to obtain a change in output voltage from O, nom to O, adj. The values of G, H, K, and L are shown in Table 5.

When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. are should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power. The output overvoltage clamp consists of control circuitry, independent of the primary regulation loop, that monitors the voltage on the output terminals. This control loop has a higher voltage set point than the primary loop (see the eature Specifications table). In a fault condition, the overvoltage clamp ensures that the output voltage does not exceed O, clamp, max. This provides a redundant voltage-control that reduces the risk of output overvoltage. Overtemperature Protection These modules feature overtemperature protection to safeguard the modules against thermal damage. When the temperature exceeds the overtemperature threshold given in the feature specifications table, the module will limit the available output current in order to help protect against thermal damage.

10 QW/Q030-Series Power Modules: dc-dc onverters; Data Sheet pril 2002 Thermal onsiderations Introduction The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat-dissipating components inside the unit are thermally coupled to the case. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the case temperature. The case temperature should be measured at the position indicated in igure (0.55) I(+) ON/O I(-) 33 (1.30) O(+) (+)SENSE TRIM (-)SENSE O( ) Note: Top view, pin locations are for reference only. Measurements shown in millimeters and (inches). igure 8. Q/QW030-Series ase Temperature Measurement Location ().a The temperature at this location should not exceed 105. The output power of the module should not exceed the rated power for the module as listed in the Ordering Information table. lthough the maximum case temperature of the power modules is 105, you can limit this temperature to a lower value for extremely high reliability. Heat Transfer Without Heat Sinks Increasing airflow over the module enhances the heat transfer via convection. igures 9 and 10 show the maximum power that can be dissipated by the module without exceeding the maximum case temperature versus local ambient temperature (T) for natural convection through 3 m/s (600 ft./min.). Systems in which these power modules may be used typically generate natural convection airflow rates of 0.3 ms 1 (60 ft./min.) due to other heat-dissipating components in the system. Therefore, the natural convection condition represents airflow rates of up to 0. 3ms 1 (60 ft./min.). Use of igure 9 is shown in the following example. Example What is the minimum airflow necessary for a QW030 operating at I = 48, an output current of 3.5, and a maximum ambient temperature of 89?

The mounting torque from the pin side must not exceed 0.25 N-m (2.2 in.-lbs.). Thermal derating with heat sinks is expressed by using the overall thermal resistance of the module. Total module thermal resistance (θca) is defined as the maximum case temperature rise ( T, max) divided by the module power dissipation (PD): θca T , max ( T T = = ) PD P D The location to measure case temperature (T) is shown in igure 8. onsult your Tyco Electronics ccount Manager or pplication Engineer for case-toambient thermal resistance vs. airflow for various heat sink configurations, heights, and orientations. Longitudinal orientation is defined as the long axis of the module that is parallel to the airflow direction, whereas in the transverse orientation, the long axis is perpendicular to the airflow. These curves are obtained by experimental testing of heat sinks, which are offered in the product catalog. These measured resistances are from heat transfer from the sides and bottom of the module as well as the top side with the attached heat sink; therefore, the case-to-ambient thermal resistances shown are generally lower than the resistance of the heat sink by itself. The module used to collect the data in the case-toambient thermal resistance curves had a thermal-conductive dry pad between the case and the heat sink to minimize contact resistance. ustom Heat Sinks more detailed model can be used to determine the required thermal resistance of a heat sink to provide necessary cooling. The total module resistance can be separated into a resistance from case-to-sink (θcs) and sink-to-ambient (θsa) as shown in igure 15. PD T TS T θcs igure 15.

The solution for heat sink resistance is: θsa = This equation assumes that all dissipated power must be shed by the heat sink. Depending on the userdefined application environment, a more accurate model, including heat transfer from the sides and bottom of the module, can be used. This equation provides a conservative estimate for such instances.
