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. 2014.06.23-A/0 Page 4 of 7 MORNSUN Guangzhou Science & Technology Co., Ltd. reserves the copyright and right of final interpretation AC/DC Converter LB(05-25)-10BxxLT Series 2.
