Note:

Output filtering capacitors C2 is 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 voltage reduced to at least 80%. C1 is ceramic capacitors, which is used to filter

high-frequency noise. TVS is a recommended component to protect post-circuits if converter fails.
