QA01C / DC-DC converter for MOSFET driver-4

DC/DC Converter for SiC Driver Dimensions and Recommended Layout THIRD ANGLE PROJECTION ($) Unit :mm[inch] 1. Packing information please refer to Product Packing Information which can be downloaded from www.mornsun-power.com. Packing 2. The lead connecting the power supply module and SiC driver should be as short as possible during use; 3. The output filtering capacitor should be as close as possible to the power supply module and SiC driver; 4. The peak of the SiC driver gate drive current is high, so low internal resistance electrolytic capacitor is recommended to be used for the power supply...
