LP3368 Description
The LP3368 charge pump LED driver is designed for powering dual channel high brightness LEDs for camera flash applications. The LP3368 automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. The LP3368 provides two current levels for TORCH and FLASH modes in each channel.
