A8500 Flexible WLED/RGB Backlight Driver

A8500 Description

A8500 Flexible WLED/RGB Backlight Driver for Medium Size LCDs .
The A8500 is a multi-output WLED driver for medium display backlighting.

A8500 Features

* ▪ Active current sharing between LED strings for ±1.5% typical current matching and ±1.2% typical accuracy ▪ Drive up to 12 series × 8 parallel = 96 LEDs (Vf = 3.2 V, If = 20 mA) ▪ Flexible dimming, using alternative methods: ▫ LED duty cycle control (PWM pin) ▫ DC current using serial programming (

A8500 Applications

* The A8500 can support any application requiring 4 to 96 WLEDs. The boost converter is a constant frequency currentmode converter. Each LED channel can sink 25 mA, and channels can be paralleled for higher currents. Flexible dimming allows output channels to either run at an adjustable DC value or w
