MAX17103 - DC-DC Converter

General Description

The MAX17103 includes a high-performance step-up regulator, a 350mA low-dropout linear regulator, a highspeed operational amplifier, a negative linear regulator controller, and a high-voltage, level-shifting scan driver.

Key Features

  • an adjustable soft-start and an adjustable cycle-by-cycle current limit. The high-current operational amplifier is designed to drive the LCD backplane (VCOM). The amplifier features high output current (±200mA), fast slew rate (50V/µs), wide bandwidth (12MHz), and rail-to-rail inputs and outputs. The low-voltage LDO linear regulator has an integrated 0.8Ω pass element and can provide at least 350mA. The output voltage is accurate within ±1%. The high-voltage, level-shifting scan driver is design.

19-4445; Rev 0; 2/09 EVAALVUAAILTAIOBNLEKIT DC-DC Converter with Integrated Scan Driver, VGL Controller, Op Amp, and LDO for TFT LCD MAX17103/AUO-P1721.14 General Description The MAX17103 includes a high-performance step-up regulator, a 350mA low-dropout linear regulator, a highspeed operational amplifier, a negative linear regulator controller, and a high-voltage, level-shifting scan driver. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications. The step-up DC-DC converter provides the regulated supply voltage for panel source driver ICs. The high 1.2MHz switching frequency allows the use of ultrasmall inductors and ceramic capacitors.
