A8504 WLED/RGB Backlight Driver

A8504 Description

A8504 WLED/RGB Backlight Driver for Medium Size LCDs .
The A8504 is a multi-output WLED driver for medium display backlighting.

A8504 Features

* ▪ Active current sharing among 8 LED strings for ±1.3% typical current matching ▪ ±1.2% typical current accuracy ▪ Drive up to 11 series × 8 parallel = 88 LEDs (Vf = 3.5 V, If = 40 mA) ▪ External PWM control for LED dimming ▪ An external resistor for LED current setting ▪ Boost converter with integr

A8504 Applications

* The boost converter is a constant frequency current-mode converter. Each LED channel can sink 45 mA, and channels can be paralleled for higher currents. LED current can be controlled with external PWM duty cycle. The A8504 is available in a 26 pin, 4 mm × 4 mm QFN/MLP package that is only 0.75 mm n
