Boost Controller For Double AA Cell or Li-Ion Battery

For White LED Application

DESCRIPTION

FEATURES

•

Voltage Mode Control with Internal

Frequency Compensation

SiP12401 is a boost controller IC for double cell NiMH or

Alkaline battery and Li Ion battery, which can drive white

LEDs connected in series to provide backlight in hand-held

devices. Series connection of the LEDs provides identical

LED currents resulting in uniform brightness and eliminating

the need for ballast resistors. For best efficiency

performance, the SiP12401 is designed to operate in PWM

mode with 600 kHz switching. The voltage-mode PWM

design is internally compensated, reducing the external

parts count. It accepts input voltages from 1.8 V to 5.0 V. The

LED current can be adjusted externally for its brightness

control. SiP12401 features low shutdown current of under

1 µA.
