Low-Cost, Multiple-Output Power Supply for LCD Monitors/TVs
General Description
The MAX8728 generates all the supply rails for thin-film
transistor (TFT) liquid-crystal display (LCD) panels in TVs and monitors.
It includes step-down and step-up
regulators, positive and negative charge pumps, and a dualmode, logic-controlled high-voltage switch control block.
The MAX8728 can operate from input voltages from 7V to 13.
2V and is optimized for LCD TV panel and LCD monitor applications running directly from 12V supplies.
The step-up and step-down
regulators feature internal power MOSFETs and high-frequency operation allowing the use of small inductors and...
