Ambient Light Adaptive LED Driver
Projeto de referência por: Texas Instruments
Ambient Light Adaptive LED Driver. The ambient light adaptive LED driver automatically adjusts display brightness for changing ambient light conditions, providing a more viewable display with better contrast. The design drives five series connected LEDs from an input voltage of 4.5V to 12V. The LED current is nominally 100mA and the output voltage is 15 to 20V
