Notes:

1. Output filtering capacitors C1, and C2 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. TVS is recommended component to protect post-circuits (when

converter fails).

2. C2 is optional and used to filter high frequency noise.
