Three-Channel Charge Pump LED Driver

Manufacturer's part number :

AAT3193IJQ-4-T1

Manufacturer Skyworks

Skyworks

Description :

The AAT3193 is a charge-pump based, current-sink white LED driver capable of driving one to three 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 AAT3193 charge pump's 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 AAT3193 is available in a 2×2.2mm, 10-lead SC70JW-10 package.
