Note:
1. 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. C1 is ceramic capacitor. it is used to filter high
frequency noise. TVS is a recommended component to protect post-circuits (if converter fails).
2. For standard EMC requirement, please refer to figure 1.If higher EMC requirement ,please refer to figure 3,
