Description

span id="lblDescription">

The AAT3192 is charge-pump based, current-sink white LED drivers capable of driving one to three LEDs up to 30mA, each. They automatically switch between 1x mode and 2x mode to maintain the highest efficiency and optimal LED current accuracy and matching.

The AAT3192 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.

The AAT3192 is available in 2x2mm 10-lead SC70JW-10 package.
