The lead connecting the power supply module and IGBT driver must as short as possible. 2. The output filtering capacitor should be connected as close as possible to the converter and the IGBT driver. 3. 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. 4. The maximum capacitive load is tested at nominal input voltage and full load. 5. Consider fixing with glue near the module if being used in vibration occasion. 6. All specifications are measured at Ta=25°C, humidity
