Note:

We recommend using an electrolytic capacitor with high

frequency, and low ESR rating for C2 (refer to manufacture’s

datasheet). Choose a Capacitor voltage rating with at least

20% margin, in other words not exceeding 80%. C1 is a ceramic

capacitor used for filtering high-frequency noise and TVS is a

recommended suppressor diode to protect the application in

case of a converter failure.
