Notes: 1. Output filtering capacitor C1 is an electrolytic capacitor. It is recommended to use high frequency
and low impedance electrolytic capacitors. For capacitance and current of capacitor please refer
to manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. C2 is ceramic
capacitor, it is used to filter high frequency noise. TVS is a recommended component to protect
post-circuits (if converter fails).
2. It is recommended to use a 2A/250V slow blow FUSE.
3. MOV is required to protect the device under surge. Varistor model: 561KD14
C3,C4: Y capacitor, recommended parameter 2,200~4,700pF/400V;
C5: X capacitor, recommended parameter 0.1~0.33ꢀF/300V;
NF: common model choke, recommended inductance is about 15mH~30mH.
