Note:
1. Output filtering capacitor C2 is electrolytic capacitor, it is recommended to use high frequency and low impedance electrolytic capacitor. For
capacitance and current of capacitor please refer to manufacture’s datasheet. Capacitor voltage reduced to at least 80%. C1 is ceramic capacitor, which
is used to filter high-frequency noise, recommended 1µF. TVS is a recommended component to protect post-circuits if converter fails.
2. EMC solution-recommended circuit
