Note:
Output filtering capacitor C2 is electrolytic capacitor, it is recommended to apply electrolytic capacitor with high frequency and low resistance. For
capacitance and current of capacitor please refer to manufacture’s datasheet. Capacitance withstand voltage derating should be 80% or above. C1 is
ceramic capacitor, which is used to filter high-frequency noise. External input MOV1 is recommended to use S14K350. TVS is a recommended component to
protect post-circuits if converter fails.
