Notes:
1. Output filtering capacitors C1, C2 and C3 are electrolytic capacitors, 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. TVS is recommended component
to protect post-circuits (if converter fails).
2. 0.1 μF is recommended for C1.
3. If a higher requirement to EMC performance is required it is recommended to add and ”EMC filter” at the input end, recommended parameter are as follows:
MOV: Varistor is used to protect the device under surge.
C7,C8:Y capacitor, recommended parameter 2200pF/400V;
C9:X capacitor, recommended parameter 0.1ꢀF/275V;
NF: common model choke, recommended inductance is about 10mH-30mH.
