Note: Output filtering capacitor C2 is electrolytic capacitors, 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. 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.
