Note:
1. C1 is ceramic capacitor, it is used to filter high frequency noise. Output filtering capacitors C2 is 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 a recommended component to protect post-circuits (if converter fails). External input NTC model is recommended to use 5D-9.
2. For standard EMC requirement, please refer to figure 1, if higher EMC requirement, please refer to figure 3 .
