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 efciency 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  
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 specications 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 VIN = 2.5V  
to 5.5V. Typical dropout voltage (2×VIN)-VOUT is shown be-  
low for several values of VIN.
