Notes:

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, and C6 are used to filter high frequency noise and it is suggested

that 0.1µF capacitors are used. TVS is recommended component to protect post-circuits (when

converter fails).

2. External input NTC is recommended to use 5D-9
