If the On/Off pin is left floating the module with be left in the OFF state. Safety Considerations For safety agency approval, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards listed on the first page of this document. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV) or ES1, the input must meet SELV/ES1 requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a fast-acting fuse with a maximum rating of 8A in the positive input lead. May 12, 2021 ©2017 General Electric Company. All rights reserved. Page 2 Tunable Loop The module is designed for 47uF capacitor on its output. For applications where more than 47uF capacitors would be used on the output, an additional Resistor (Rtune) and Capacitor (Ctune) would be required in the circuit schematic to compensate for the additional capacitance. The placement is between the Sense+ pin and Trim pin as per figure below: Figure. 3. Circuit diagram showing connection of RTUNE and CTUNE to tune the control loop of the module The recommended values for Rtune and Ctune for different amounts of external capacitance are as per the table below: Co RTUNE 1x10F 1x22F 2x22F 4x22F 6x22F 330Ω 270Ω 220Ω 180Ω 180Ω CTUNE 330pF 680pF 1500pF 2700pF 3.3nF Recommended Pad Layout Dimensions are in millimeters and (inches).

If such an assembly is attempted, components may fall off the module during the second reflow process Lead Free Soldering Peak Temp 260°C 250 Reflow Temp (°C) The minimum recommended inside nozzle diameter for reliable operation is 3mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 7 mm. 200 * Min. Time Above 235°C 15 Seconds Cooling Zone 150 Heating Zone 1°C/Second *Time Above 217°C 60 Seconds 100 50 0 The modules are lead-free (Pb-free) and RoHS compliant and fully compatible in a Pb-free soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability MSL Rating The modules have a MSL rating of 2a. Pb-free Reflow Profile Power Systems will comply with J-STD-020 Rev. D (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The following profile is the recommended linear reflow profile using Sn/Ag/Cu solder. Soldering outside of the recommended profile requires testing to verify results and performance. Reflow Time (Seconds) Storage and Handling J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices) is recommended. Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of  30°C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40° C, < 90% relative humidity. 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.
