The device is optimized for driving 1 to 4 high power white LEDs in parallel with a maximum current of 800mA.
Maximum efficiency is achieved over the input voltage range by actively selecting the proper gain based on the LED forward voltage and current requirements.
Two external low power resistors set the desired current for Torch and Flash modes.
The TX pin allows the...
