Semtech SC1462A

High Efficiency Charge Pump Doubler

The SC1462A is a versatile charge pump designed for use in battery operated power supply applications over the wide input range of 1.65 to 5.5 volts.  A simple, low quiescent current charge pump doubler can be implemented without costly inductors or capacitors. Internal MOSFETs and control circuitry eliminate the need for costly board space and design time.
