Note:
Output filtering capacitor C2 is electrolytic capacitor, it is recommended to apply electrolytic capacitor with high frequency and low resistance. For
capacitance and current of capacitor please refer to manufacture’s datasheet. Capacitance withstand voltage derating should be 80% or above. C1 is
ceramic capacitor, advice use 1μF.which is used to filter high-frequency noise. TVS is a recommended component to protect post-circuits if converter fails.
