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 is recommended
to use 1A/300V; external input MOV is recommended to use S14K350; external input NTC
is recommended to use 10D-11; external input CX is recommended to use 0.47μF/305VAC.
