Typical application circuit AC(L) +Vo -Vo AC(L) AC(N) AC(N) C1 C2 TV S LOAD FUSE AC /D C MO V1 NTC Fig. 1 Model C1(μF) C2(μF) TVS tube LH60-20B05(-DT) 1 680 SMBJ7.0A LH60-20B09(-DT) 470 SMBJ12A LH60-20B12(-DT) 330 SMBJ20A LH60-20B15 330 SMBJ20A LH60-20B24 200 SMBJ30A LH60-20B48 100 SMBJ64A Note: 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 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. External input FUSE model is recommended to use 3.15A/250VAC, slow fusing. External input NTC model is recommended to use 5D-9. External input MOV model is recommended to use S14K350. 2.
