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.

The SC1464 charge pump can be used for applications that require up to 60mA of output current with V_IN = 2.85V and V_OUT = 5.2V. The small 8 lead MSOP-8 package helps minimize board space.

The TF1 and TF2 pins provide binary control of the oscillator frequency to either 1 MHz, 260kHz, 32kHz or 8kHz. The user can change the frequency during operation with extremely fast settling time.
