LT3003 - 3-Channel LED Ballaster With PWM

The LT3003 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.
The LT3003 operates in boost, buck and buck-boost mode. A True Color PWM Dimming ratio of up to 3000:1 is achievable using a logic-level signal at the PWM pin for all modes without the need for external level-shifting circuitry. For applications with input supply above and below the output voltage of the LED strings, the LT3003 allows the LEDs to be returned to the input supply (buck-boost mode) instead of being limited to only SEPIC solutions.
The LT3003 is ideal for high power LED Driver applications such as TFT LCD backlighting and heads-up Displays Additional overtemperature outputs allow appropriate system management for increased reliability.
The LT3003 is available in a small 10-pin MSE package.
