Description:

4-Channel Charge Pump White LED Driver

Features

* Input Voltage Range: 2.7V to 5.5V
* Drives up to 4 LEDs at 20mA Each
* 16-Step Brightness Control
* High Efficiency by Fractional Conversion with 1× and 1.5× Modes
* Automatic Charge Pump Mode Selection
* Switching Frequency: 1MHz
* 1% Typical LED Current Matching

Applications

* User can easily configure each LED current from 1.25mA to 20mA by a pulse dimming control. The dimming of white LEDs current can be achieved by applying a pulse signal to the EN/SET pin. There are totally 16 steps of current could be set by users. The operating voltage range is 2.7V to 5.5V. Intern
