DESCRIPTION

The SC1464 is a versatile charge pump designed for use in battery operated power supply applications. A simple, low current charge pump doubler can be implemented without costly inductors or capacitors. Internal MOSFET’s and control circuitry eliminate the need for costly board space and design time. The small device footprint allows for compact circuit design.
