DESCRIPTION
The SC1660 is a monolithic CMOS switched capacitor voltage converter. Designed to be an improved direct replacement for the popular 7660, the SC1660 provides performance superior to previous designs by combining low quiescent current with high efficiency, and by eliminating diode drop voltage losses. The only required external components are two low cost electrolytic capacitors.
