IS31BL3231, FLASH LED DRIVER

IS31BL3231 FLASH LED DRIVER July 2015 GENERAL .
The IS31BL3231 is a current-regulated charge pump and ideal for powering high brightness LEDs for camera flash and torch applications.

Features

* Operates from 2.7V to 5.5V
* Up to 90% efficiency in Torch Mode
* Output current up to 750mA
* Adjustable output current in Flash Mode
* Minimum external components, no external inductor required
* Automatic boost mode
* Less than 1µA shutdown current
* Low ripple a

Applications

* The charge pump can be set to regulate two current levels for FLASH and TORCH modes. The IS31BL3231 automatically switches between linear and boost modes ensuring that LED current does not depend on the LED forward voltage. IS31BL3231 provides low cost, space saving solution for driving LED. It als
