LT3003E Datasheet - Linear Technology

DESCRIPTION
The LT®3003 drives three separate strings of LEDs up to 350mA/channel with 3% accurate current matching, resulting in uniform LED brightness and intensity. This approach is superior to conventional methods of running three separate channels with external ballast resistors requiring expensive factory calibration.

FEATURES
■ 3% LED Current Matching
■ Up to 350mA Continuous Current per LED String
■ Up to 3000:1 True Color PWMTM Dimming Range
■ PWM Input Disconnects LED Strings
■ Can Operate in Buck, Boost and Buck-Boost Modes
■ Wide Input Range: 3V to 40V
■ Overtemperature Outputs
■ Works with LT1618, LT3477, LT3474, LT3475, LT3476, LTC®3783
■ Thermally Enhanced 10-Pin MSOP Package

APPLICATIONS
■ High Power LED Ballaster
■ Automotive Lighting
