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.
