General Description
The MAX17126/MAX17126A generate all the supply rails for thin-film transistor liquid-crystal display (TFT LCD) TV panels operating from a regulated 12V input. They include a step-down and a step-up regulator, a positive and a negative charge pump, an operational amplifier, a high-accuracy high-voltage gamma reference, and a high-voltage switch control block. The MAX17126/ MAX17126A can operate from input voltages from 8V to 16.5V and is optimized for an LCD TV panel running directly from 12V supplies.
