A8508 Datasheet (Allegro) - 8-Channel Fault Tolerant LED Driver

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
