FP6773 Description
The FP6773 Buck/Boost charge pump LED driver is designed for powering high brightness white LEDs for camera flash applications. The FP6773 automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. The FP6773 provides two current levels for TORCH and FLASH modes.
