DESCRIPTION
The SC1462 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 imple-
mented without costly inductors or capacitors. Internal
MOSFETs and control circuitry eliminate the need for
costly board space and design time. The small 6 lead
SOT-23 package helps minimize board space.
The SC1462
charge pump can be used for applica-
tions that require up to 80mA of output current with V
IN
= 2.5V to 5.5V. Typical dropout voltage (2*Vin-Vout) is
shown below for several values of Vin.
