Description : Boost Controller FOR Double AA Cell or LI-ION BATTERY FOR White LED APPLICATION

DESCRIPTION
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.

FEATURES
• Voltage Mode Control with Internal Frequency Compensation
• 1.8 V to 5.0 V Input Voltage Range
• PWM Control with 600 kHz Fixed Switching Frequency
• Analog Control of LED Intensity
• Regulated Output Current
• Integrated UVLO and Soft-Start
• Logic ControlLED Shutdown (< 1 µA)
• High Efficiency: Typical 80 %
• PowerPAK® MLP33-6 Package

APPLICATIONS
• White LED Backlighting
• LCD Bias Supplies
• Handheld Devices
• Digital Cameras
• Portable APPLICATIONs
