LT3465AES6

LED Driver 6Segment 3.3V/5V/9V/12V/15V 6Pin TSOT-23

DESCRIPTION

The LT® 3465A is a step-up DC/DC converter designed to drive up to six LEDs in series from a Li-Ion cell. Series connection of the LEDs provides identical LED currents and eliminates the need for ballast resistors. This device  integrates the Schottky diode required externally on competing devices. Additional features include output voltage limiting when LEDs are disconnected, one-pin shutdown and dimming control.

FEATURES

■ Inherently Matched LED Current

■ Drives Up to Six LEDs from a 3.6V Supply

■ No External Schottky Diode Required

■ Open LED Protection

■ High Efficiency: 79% Typical

■ Requires Only 0.22µF Output Capacitor

■ Switching Frequency Above AM Broadcast Band

■ Low Profile <1mm SOT-23 Packaging

APPLICATIONS

■ Cellular Phones

■ PDAs, Handheld Computers

■ Digital Cameras

■ MP3 Players

■ GPS Receivers
