AAT3103 Three-Channel Charge-Pump LED Driver

AAT3103 Description

General .
The AAT3103 is a constant frequency charge-pump based current-source white LED driver capable of driving one to three LEDs up to 30mA, each.

AAT3103 Features

* Source WLED Driver, up to 3 LEDs at up to 30mA, each
* Automatic Switching Between 1x and 2x Modes
* 900KHz Switching Frequency
* Linear LED Output Current Control ▪ Single-wire, S2Cwire Interface
* AAT3103-1: 16-step
* AAT3103-2: 8-step ▪ ON/OFF or PWM Inte

AAT3103 Applications

* The AAT3103-1/-2 uses Skyworks' Simple Serial Control (S2Cwire™) interface to enable, disable, and program the LED driving current. The AAT3103-4 employs a Pulse Width Modulation (PWM) signal with up to 50kHz frequency, 10% to 100% duty cycle to program the LED current. A low-current shutdown featu
