DC/DC Converter for IGBT Driver QAxxxD Series Design Reference 1. Typical application IGBT Driver Control Signal 100uF/35V (Low internal resistance capacitance) Note: C3 and C5 can be select a capacitance value in 1uF~10uF ceramic capacitors. Can be appropriately increased values of C2 and C4 ,but less than Max. Capacitive Load of the product ,in order to reduce the ripple&noise. 2. It is not allowed to connect modules output in parallel to enlarge the power 3.

DC/DC Converter for IGBT Driver QAxxxD Series Packing information please refer to Product Packing Information which can be downloaded from www.mornsun-power.com. Packing bag number: 58210008; The lead wire connecting the power supply module and IGBT driver should be as short as possible during use; The input&output filtering capacitor should be as close as possible to the power supply module and IGBT driver; The peak of the IGBT driver gate drive current is high, so low internal resistance electrolytic capacitor is recommended to be used for the power supply module output filter capacitor;...
