The converter incorporates synchronous rectification technology and innovative packaging techniques to achieve high efficiency reaching 91% at 3.3V full load. The ultra high efficiency of this converter leads to lower power dissipation such that for most applications a heat sink is not required. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for both input and output minimizes the need for external filtering. October 5, 2015 ©2012 General Electric Company. All rights reserved. Data Sheet GE JRW017-070 Series Power Modules DC-DC Converters 36-75Vdc Input; 1.2Vdc to 12Vdc Output Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of 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 time-delay fuse with a maximum rating of 20A (see Safety Considerations section). Based 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. Refer to the fuse manufacturer’s data sheet for further information. October 5, 2015 ©2012 General Electric Company. All rights reserved.

A highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 43, a 100μF electrolytic capacitor (ESR< 0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines. Note: Measure input reflected-ripple current with a simulated source Output Capacitance inductance (LTEST) of 12 µH. Capacitor CS offsets possible battery impedance. Measure current as shown above. High output current transient rate of change (high di/dt) loads may require high values of output capacitance to Figure 43. Input Reflected Ripple Current Test Setup. supply the instantaneous energy requirement to the load. To minimize the output voltage transient drop during this transient, low E.S.R. (equivalent series resistance) capacitors may be required, since a high E.S.R. will produce a correspondingly higher voltage drop during the current transient. Output capacitance and load impedance interact with the power module’s output voltage regulation control system and may produce an ’unstable’ output condition for the required values of capacitance and E.S.R.. Minimum and maximum values of output capacitance and of the capacitor’s associated E.S.R. may be dictated, depending on the module’s control system. Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or tantalum The process of determining the acceptable values of capacitor. Scope measurement should be made using a BNC socket. capacitance and E.S.R. is complex and is load- Position the load between 51 mm and 76 mm (2 in. and 3 in.) from the module. dependant.

Safety Considerations For 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., † UL* 60950-1 Recognized, CSA C22.2 No. 60950-3-01 ‡ Certified, and EN 60950-1 (VDE 0805): 2001-12 Licensed. Note: All measurements are taken at the module terminals. When socketing, place Kelvin connections at module terminals to avoid measurement errors due to socket These converters have been evaluated to the spacing contact resistance. requirements for Basic Insulation per the above safety standards.

For all input voltages, other than DC MAINS, where the input voltage is less than 60V dc, if the input meets all of the requirements for SELV, then:  The output may be considered SELV. Output voltages will remain within SELV limits even with internally-generated non-SELV voltages. Single component failure and fault tests were performed in the power converters.  One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. For all input sources, other than DC MAINS, where the input voltage is between 60 and 75V dc (Classified as TNV-2 in Europe), the following must be meet, if the converter’s output is to be evaluated for SELV:  The input source is to be provided with reinforced insulation from any hazardous voltage, including the ac mains.  One Vi pin and one Vo pin are to be reliably earthed, or both the input and output pins are to be kept floating.  Another SELV 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. The power module has ELV (extra-low voltage) outputs when all inputs are ELV. All flammable materials used in the manufacturing of these modules are rated 94V-0. The input to these units is to be provided with a maximum 20A fast-acting (or time-delay) fuse in the unearthed lead. October 5, 2015 ©2012 General Electric Company. All rights reserved.

Page 17 Data Sheet GE JRW017-070 Series Power Modules DC-DC Converters 36-75Vdc Input; 1.2Vdc to 12Vdc Output Thermal Considerations The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. Heat-dissipating components are mounted on the topside of the module. Heat is removed by conduction, convection and radiation to the surrounding environment. Proper cooling can be verified by measuring the thermal reference temperature (Tref ). The peak temperature (Tref ) occurs at the position indicated in Figures 50 - 52. The temperature at any one of these T locations should not exceed per below table to ensure ref1 reliable operation of the power module. Figure 51. Tref Temperature Measurement Location for Vo= 5V.

Although the maximum T temperature of the power ref modules is approximately 117 °C, you can limit this temperature to a lower value for extremely high reliability.

As such, component clearances between the bottom of the power module and the mounting board are limited. Either avoid placing copper areas on the outer layer directly underneath the power module or maintain a minimum clearance through air of 0.028 inches between any two “opposite polarity” components, including copper traces under the module to components on the JRW module.. For modules with a “7” (case (heatplate) pin) and “-H” (heatplate) option: To meet Basic Insulation in the end product 1) between the input and output of the module, or 2) between the input and the earth ground, a series capacitor (capable of withstanding 1500V dc) needs to inserted between the case pin and the end termination point, if the case pin is connected to the input or the output of the JRW module or to earth ground. For additional layout guide-lines, refer to FLTR100V10 data sheet. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to GE Board Mounted Power Modules: Soldering and Cleaning Application Note (AP01-056EPS). Through-Hole Lead-Free Soldering Information The RoHS-compliant through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHS- Mechanical Outline Dimensions are in millimeters and (inches).
