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.
