Low-Cost, Multiple-Output Power Supply for LCD TVs
MAX17113
General Description
The MAX17113 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, a Dual Modeā¢ logiccontrolled high-voltage switch control block, and an adjustable-timing power-good output. The MAX17113 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.
The step-up and step-down
regulators feature internal power MOSFETs and high-frequency operation allowing the use of small inductors and capacitors, resulting in a compact solution. Both switching
regulators use fixed-frequency current-mode control architectures, providing fast load-transient response and eas...
