Only two external capacitors can work polarity power conversion ICL7660

Consisting of two capacitors polarity as shown by ICL7660 and external power conversion. The power supply using a dedicated integrated circuit ICL7660 polarity inversion and ex

ternal charge pump capacitor constituted of two DC/DC voltage polarity reversal. High conversion efficiency, 95%, power consumption is small. Quiescent current of 0.5mA, the output current is 10 ~ 20mA.
