Maxim MAX17014低成本LCD TV电源解决方案
Maxim 公司的MAX17014是低成本多输出的LCD TV电源控制器，能从12V中产生TFT-LCD TV和监视器中所需要的电压，包括降压和升压稳压器，正和负电荷泵，两个运算放大器，以及Dual Mode逻辑控制高压控制区块。MAX17014输入电压从8V到16。5V，可调整的输出电压低到1.25V，精度1%，内置20V/3.3A的110毫欧姆的N-MOSFET，主要用于LCD TV屏和LCD监视器屏。本文介绍MAX17014主要特性，方框图，正和负电荷泵稳压器方框图，简化工作电路图以及典型工作电路图和所用的元件列表。
MAX17014：Low-Cost Multiple-Output Power Supply for LCD TVs
The MAX17014 multiple-output power-supply controller generates all the supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) panels in TVs and monitors operating from a regulated 12V input. It includes a step-down and a step-up regulator, a positive and a negative charge pump, two operational amplifiers, and a Dual Mode™ logic-controlled highvoltage switch control block. The MAX17014 can operate from 8V to 16.5V input voltages and is optimized for LCD TV panel and LCD monitor applications running directly from 12V supplies.
