Typical application circuit AC(L) +Vo -Vo AC(L) AC(N) AC ( N) C1 C2 TVS RL FU SE AC DC MOV1 NT C Fig. 1 Model FUSE NTC MOV1 C1 C2 TVS LD12-20B03 3.15A slow fusing 10D-11 S20K350 1μF/50V 220μF/10V SMBJ7.0A LD12-20B05 220μF/10V SMBJ7.0A LD12-20B12 120μF/25V SMBJ20A LD12-20B15 120μF/25V SMBJ20A LD12-20B24 68μF/50V SMBJ30A 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. TVS is a recommended component to protect post-circuits if converter fails. 2.
