Overview

PRODUCT DATASHEET AAT3104178 ChargePumpTM General Description The AAT3104 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 accuracy and matching.
The AAT3104 charge pump’s 1x mode (bypass mode) has very low resistance allowing LED current regulation to be maintained with input supply voltage approaching com the LED forward voltage.
LED brightness is controlled using AnalogicTech’s patented S2Cwire™ single wire interface.
The AAT3104 is available in a 2x2mm 10-lead SC70JW-10 package.
