DESCRIPTION

The LT®3497 is a dual full function step-up DC/DC converter specifi cally designed to drive up to 12 white LEDs (6 white LEDs in series per converter) from a Li-Ion cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors and expensive factory calibration.

FEATURES

■ Drives Up to 12 White LEDs (6 in Series per

Converter) from a 3V Supply

■ Two Independent Boost Converters Capable of

Driving Asymmetric LED Strings

■ Independent Dimming and Shutdown Control of the

Two LED Strings

■ High Side Sense Allows “One Wire Current Source”

per Converter

■ Internal Schottky Diodes

■ Open LED Protection (32V)

■ 2.3MHz Switching Frequency

■ ±5 Reference Accuracy

■ VIN Range: 2.5V to 10V

■ Dual Wide 250:1 True Color PWMTM Dimming

■ Requires Only 1µF Output Capacitor per Converter

■ Available in a 3mm × 2mm 10-Pin DFN Package

APPLICATIONS

■ Cellular Phones

■ PDAs, Handheld Computers

■ Digital Cameras

■ MP3 Players

■ GPS Receivers
