AAT2822中文资料TFT-LCD DC-DC Converter with WLED Driver and VCOM Buffer数据手册Skyworks规格书

描述 Description

The AAT2822-AAT2825 family of integrated panel power solutions provides the regulated voltages required by an active-matrix thin-film transistor (TFT) liquid-crystal display (LCD). The AAT2822 includes a triple-output DC/DC converter, a LED backlight driver, and a VCOM buffer in a 4 mm x 4mm TQFN package. This family is ideally suited for powering and backlighting 5” to10” LCD display products.

特性 Features

·Efficient:  The AAT2822’s boost converter architecture improves efficiency to charge pump only implementation.
·Flexible:  The 28V WLED backlight driver supports high voltage serial and parallel configured LED strings.
·Powerful:  The backlight driver can deliver up to 260mA of continuous current.
·Safe & Easy: The  built-in supply sequencing and fault detection prevents damage to LCD.
·Solution footprint smaller than 30mm x 20mm due to system integration and support for small inductors and capacitors.

简介

AAT2822属于集成电路（IC）的LED驱动器。由制造生产的AAT2822LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
