- Notes: 7. C1 is a ceramic capacitor used to filter high frequency noise. 

8. C2 is an electrolytic capacitor and it is recommended to be high frequency and low impedance. For capacitance and current of capacitor, refer to the datasheet provided by the 

manufacturer. Voltage derating of capacitor should be at least 80%. 

   9. TVS is a recommended component to protect post-circuits (if converter fails).
