A8508 8-Channel Fault Tolerant LED Driver

The A8508 is a multi-output white LED driver for backlighting LCD panels. It integrates a current-mode boost controller and eight individual current sinks. The boost controller architecture allows for significant scaling of boost voltage to optimize the solution for the required number of LEDs per s.

A8508 Features

* Eight integrated high current sinks for LED strings; can be tied together for even higher currents

* Fixed frequency current mode control with integrated gate driver / boost controller; powerful gate driver to drive an external N-channel MOSFET allows significant scaling capability
