DESCRIPTION  
FEATURES  
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 imple-  
mented 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.  
= Small size - MSOP-8 package  
= Typical efficiency of 90% @ full load  
= Designed to work with ceramic or tantalum  
capacitors  
= Soft start functionality  
= Short-Circuit and Over-Temperature protection  
= <55µA input current @ no load (TF1=0;TF2=1)  
= <330µA input current @ no load (TF1=0;TF2=0)  
= Oscillator frequency accurate to ±5%  
= Shutdown current < 1µA  
The SC1464 charge pump can be used for applications  
that require up to 60mA of output current with VIN  
=
2.85V and VOUT = 5.2V. The small 8 lead MSOP-8  
package helps minimize board space.  
= All Specifications rated over the full temperature  
range (-40°C to 85 °C)  
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 oper-  
ation with extremely fast settling time.  
APPLICATIONS  
= Cellular phones  
= Handheld devices  
= PDA power supplies  
= Peripheral card supplies
