Linear Technology LT3003
The LT3003 operates in boost, buck and buck-boost mode. 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.| Part No. | LT3003 |

● LT3003 3-Channel LED Ballaster with PWM
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. 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. Additional overtemperature outputs allow appropriate system management for increased reliability. The LT3003 is available in a small 10-pin MSE package. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation. True Color PWM is a trademark of Linear Technolology Corporation.
