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 Mode™ 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.

Overview

MAX17014 19-1045; Rev 1; 11/09 EVAALVUAAILTAIOBNLEKIT Low-Cost Multiple-Output Power Supply for LCD TVs.

Key Features

high output current (±150mA), fast slew rate (100V/µs), wide bandwidth (20MHz), and rail-to-rail inputs and outputs. A series p-channel MOSFET is integrated to sequence power to AVDD after the MAX17014 has proceeded through normal startup, and provides True Shutdown™. The MAX17014 is available in a small (7mm x 7mm), low-profile (0.8mm), 48-pin thin QFN package and operates over a -40°C to +85°C temperature range. LCD TV Panels LCD Monitor Panels.
