A8508 - 8-Channel Fault Tolerant LED Driver

General Description

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.

Key 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 on the number of LEDs per string.
  • Parallel operation capability with one boost controller (master) and up to three additional slave controllers; can run up to 32 strings of LEDs while popula.
