A8512 LED Backlight Driver

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. PWM dimming allows LED currents.

A8512 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
