    Description

    The A8504 is a multi-output WLED driver for medium display backlighting. The A8504 integrates a boost converter and eight current-sinks to provide a WLED/RGB backlight driver. The boost converter can provide output voltage up to 47 V. The flexible channel selection control and high voltage capability allow a wide range of LED backlight 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 nominal in height. Applications include:

    • Thin notebook displays
    • LCD TV
    • RGB backlight
    • GPS systems
    • Portable DVD players
