The A8500EECTR-T is a flexible WLED/RGB backlight driver designed for medium-sized LCD applications. It features a boost converter capable of delivering output voltages up to 47 V and supports driving up to 96 LEDs with a maximum current of 25 mA per channel. The device allows for active current sharing between LED strings, ensuring a typical current matching of ±1.5% and accuracy of ±1.2%. Dimming options include LED duty cycle control via a PWM pin, DC current adjustment through serial programming, and external PWM signals. The A8500 incorporates several protection features such as open LED disconnect, boost current limit, thermal shutdown, and adjustable overvoltage protection. It is housed in a compact 26-pin QFN/MLP package measuring 4 mm x 4 mm and is suitable for applications including thin notebook displays, LCD TVs, RGB backlighting, GPS systems, and portable DVD players. However, it is important to note that this product has been discontinued as of September 30, 2024, and should not be purchased for new design applications.
