MAX17126B Datasheet Multi-Output Power Supplies

Manufacturer: Maxim Integrated (now Analog Devices)

General Description

The MAX17126B generates all the supply rails for thinfilm 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 highaccuracy high-voltage gamma reference, and a highvoltage switch control block.

The device can operate from input voltages from 8V to 16.5V and is optimized for an LCD TV panel running directly from 12V supplies.
