GENERAL DESCRIPTION
FEATURES
Input Voltage Range: 2.7V to 5.5V The LP3367 buck/boost charge pump LED driver is Adjustable FLASH Mode Current designed for powering high brightness white LEDs for Output Current up to 1A camera flash applications. The LP3367 automatically Up to 95% Efficiency in TORCH Mode switches modes between step-up and step-down Automatic Buck/Boost Mode Switchover ensuring that LED current does not depend on the Minimum External Components: No Inductors forward voltage. The LP3367 provides two current <1uA Quiescent Current levels for TORCH and FLASH modes. In TOUCH 2 MHz High Frequency Operation mode, The LED 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 LP33
