MAX17126 - Multi-Output Power Supplies

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.

Key Features

  • high output current (Q200mA), fast slew rate (45V/Fs), wide bandwidth (20MHz), and rail-to-rail outputs. Also featured in the MAX17126/MAX17126A is a highaccuracy, high-voltage adjustable reference for gamma correction. The MAX17126/MAX17126A are available in a small (7mm x 7mm), ultra-thin (0.8mm), 48-pin thin QFN package and operate over the -40NC to +85NC temperature range. LCD TV Panels.

MAX17126/MAX17126A 19-4681; Rev 1; 3/10 EVAALVUAAILTAIOBNLEKIT Multi-Output Power Supplies with VCOM Amplifier and High-Voltage Gamma Reference for LCD TVs 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.
