NOTES
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.
