Note:

Note: Output filtering capacitors C2, C4, C6 are electrolytic capacitors, it is recommended to use high frequency and low impedance electrolytic capacitor.

For capacitance and current of capacitor please refer to manufacture’s datasheet. Capacitor withstand voltage derating should be 80% or above. C1,C3, C5

are ceramic capacitors, which is used to filter high-frequency noise,advice use 1μF. TVS is a recommended component to protect post-circuits if converter

fails.External input MOV model is recommended to use S14K300.
