SC1462

High Output Current

Charge Pump Doubler

POWER MANAGEMENT

Description

Features

Input supply voltage range of 1.65V to 5.5V

Small size - 6 pin SOT-23 package

Typical efﬁciency of :

91% @ V_IN= 2.5V, I_OUT= 45mA

94% @ V_IN= 3.6V, I_OUT= 55mA

Short circuit and over-temperature protection

140μA typical input current @ no load

Shutdown current <1μA

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 qui-

escent 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. The small 6 lead SOT-23 package

helps minimize board space.

Designed to work with ceramic or tantalum

capacitors

Fixed frequency of 160kHz

All speciﬁcations rated over full temperature range

(-40°C to 85°C)

The SC1462 charge pump can be used for applications

that require up to 80mA of output current with V_IN= 2.5V

to 5.5V. Typical dropout voltage (2×V_IN)-V_OUTis shown be-

low for several values of V_IN.
