The AAT3105 is a charge-pump based, current-source white LED driver capable of driving one to four LEDs up to 30mA, each. It automatically switches between 1x mode and 2x mode to maintain the highest efficiency and optimal LED current matching.
The AAT3105 charge pump 1x mode (bypass mode) has very low resistance, allowing LED current regulation to be maintained with input supply voltage approaching the LED forward voltage.
LED brightness is controlled using a universal PWM interface. The AAT3105 is available in a Pb-free, 2x2.1mm 10-lead SC70JW-10 package.
