Fiti FP6773
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.| Part No. | FP6773 |

DESCRIPTION
In TORCH mode, the current sense reference voltage is 50mV. The LED current can be determined by current sense resistor. In Flash mode, the current sense reference voltage can be adjusted by external resistor. The maximum LED current can be set up to 1A. The FP6773 is available in a space saving TDFN-10 3mm×3mm package. FP6773 85T Buck/BoostFEATURES
