A8512 - LED Backlight Driver

General Description

The A8512 is a multi-output WLED/RGB driver for backlighting LCD monitors and televisions.

It integrates a boost controller to drive external MOSFET, and six internal currentsinks.

The boost converter operates in constant frequency (programmable) current mode control.

Key Features

  • Six integrated high current sinks.
  • Fixed frequency current mode control with integrated gate driver.
  • 300 kHz to 1 MHz adjustable switching frequency.
  • Controlled startup using options of Enable, PWM signal, or battery voltage ramp.
  • Parallel operation with one boost controller (master) and up to five slave controllers.
  • Active current sharing between LED strings for ±0.6% accuracy and matching.
  • No audible MLCC noise during PWM dimming.
  • Adjustable overvoltage.
