RECOMMENDED TEST AND APPLICATION CIRCUIT
1. TVS&FUSE be helpful with over voltage protection and inrush limiting. Recommended FUSE better be 1.5~2times of the
rated current .
2. The input filter capacitor C6 could select the aluminum electrolytic capacitors or tantalum capacitors, and the withstand
voltage should be greater than the highest input voltage. Recommended capacitor should be between 22μF~100μF.
3. C1,C2 for the input filter capacitor,0.1~1μF high-frequency ceramics capacitor or chip capacitor are recommended. The
withstand voltage of output filter C5, C7 should be greater than the highest output voltage. Recommended capacitor of C7
better within 100μF and C5 connected with the chip to reduce the input voltage peak, recommended 0.1~1μF
high-frequency ceramics capacitor or chip capacitor.
