C1: Ceramic capacitor with 1µF capacitance. b. C2: Capacitor suitable for fixed input products. Please refer to datasheet. Normally 10µF is recommended. c. Distance between two paralleled copper foils is 2.5mm of which the sum of voltage drops should be less than 2% of nominal voltage. Notes: 1. The lead connecting the power supply module and SiC driver must as short as possible. 2. The output filtering capacitor should be connected as close as possible to the converter and the SiC driver. 3. 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 module output filter capacitor. 4. The average output power of the driver must be lower than that of the power supply module. 5. The maximum capacitive load is tested at nominal input voltage and full load. 6. Consider fixing with glue near the module if being used in vibration occasion. 7. All specifications are measured at Ta=25°C, humidity
