DESCRIPTION

FEATURES

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.

•= Input supply voltage range of 1.65V to 5.5V

•= Small size - 6 pin SOT-23 package

•= Typical efficiency of :

91% @ Vin = 2.5V, Iout = 45mA

94% @ Vin = 3.6V, Iout = 55mA

•= Short circuit and over-temperature protection

•= 140µA typical input current @ no load

•= Shutdown current <1µA

•= Designed to work with ceramic or Tantalum

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.

capacitors

•= Fixed frequency of 160kHz

•= All specifications rated over full temperature

range (-40°C to 85°C)
