TYPICAL APPLICATIONS
Note:
1. Output filtering capacitors C1 is ceramic capacitor, it is used to filter high frequency noise. C2 is electrolytic capacitors, It is recommended to use high frequency
2. For standard EMC requirement, please refer to figure 1, if higher EMC requirement, please refer to figure 3 or figure 4.
3.
PCB MOUNTING WITH SOLDER PINS
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 a recommended component to protect post-circuits (if converter fails). External input NTC model is recommended to use 5D-9.
FUSE：LD10 is recommended to use 2A/250V.
