REVISION HISTORY
Notes: 1. Output fi ltering 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 fi lter high frequency noise. TVS is a recommended component to protect
post-circuits (if converter fails).
2. MOV is required to protect the device under surge.
2. It is recommended to use a 2A/250V slow blow FUSE. External input NTC is recommended to
use 5D-9.
3. If EMC performance is required, it is recommended to add “EMC fi lter” at the input end (see EMC
Application Figure).
C6: X capacitor, recommended parameter 0.1F/275V;
C7,C8: Y capacitor, recommended parameter 2200pF/400V;
NF: common model choke, recommended inductance is about 10mH-30mH.
