Maxim MAX8784 TFT-LCD电源解决方案
Maxim 公司的MAX8784是TV和监视器的TFT-LCD电源解决方案，包括升压稳压器，调整的正和负电荷泵，三个大电流运输放大器，以及双模式逻辑控制高压开关控制区块。输入电压4V-5.5V。效率高达90%，开关频率1.2MHz，主要用在LCD TV和LCD 监视器。本文介绍了MAX8784主要特性，方框图，典型工作电路图和所用元件列表，MAX8784评估板主要特性，电路图和评估板元件列表。
The MAX8784 generates supply rails for the thin-film transistor (TFT) liquid-crystal display (LCD) panels in TVs and monitors. It includes a step-up regulator, a regulated positive and a negative charge-pump, three high-current operational amplifiers, and Dual Mode™, logic-controlled, high-voltage switch control block. HVS mode automatically increases the output voltages of the boost regulator and the positive charge-pump to stress test display panels during production. The MAX8784 can operate from input voltages of 4V to 5.5V and is optimized for LCD TV panel and LCD monitor applications.
