Description
General part information
LM3632A Series
The LM3632A integrates the WLED drivers for both the backlight of the LCD panel and the camera flash along with the bias power for the LCD panel into one device. The device has all the safety features required in LED drivers with up to 90% efficiency and bias positive/negative power rails achieving 1.5% accuracy. Capable of driving up to 16 backlight LEDs, the device is ideal for small- to medium-size displays. A 1.5-A constant-current LED driver powered by a synchronous boost converter can be used for flash applications. The high-side flash current source allows for grounded cathode LED operation.
A high level of integration and programmability allows the LM3632A to address a variety of applications without the need for hardware changes.
