Low-Cost Multiple-Output Power Supply for LCD TVs
General Description
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 Modeā¢ 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.
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 easy compensati...
