Remarks:
1. Output filtering capacitors C1, C2 and C3 are 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. C2,C4,C6 are use to filter
high frequency noise. TVS is recommended component to protect post-circuits(when converter fails).
2. External input NTC is recommended to use 5D-9 ( Only MA10 models and MA15 models)
