Note:
Output ltering 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 lter high-frequency noise. External
input MOV1 is recommended to use S14K350. TVS is a recommended component to protect
post-circuits if converter fails.
