MAX1711EEG

Product Summary

The MAX1711EEG is a kind of low-cost, multiple-output power supply for LCD TVs. The MAX1711EEG 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. The MAX1711EEG includes a step-down and a step-up regulator, a positive and a negative charge pump, a Dual Mode logiccontrolled high-voltage switch control block, and an adjustable-timing power-good output. The MAX1711EEG 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.
