MAX1518B - TFT-LCD DC-DC Converter

General Description

The MAX1518B includes a high-performance step-up regulator, two linear-regulator controllers, and high-current operational amplifiers for active-matrix, thin-film transistor (TFT), liquid-crystal displays (LCDs).

Also included is a logic-controlled, high-voltage switch with adjustable delay.

Key Features

  • high output current (±150mA), fast slew rate (13V/μs), wide bandwidth (12MHz), and rail-to-rail inputs and outputs. The MAX1518B is available in a 32-pin thin QFN package with a maximum thickness of 0.8mm for ultra-thin LCD panels.

MAX1518B EVALUATION KIT AVAILABLE TFT-LCD DC-DC Converter with Operational Amplifiers General Description The MAX1518B includes a high-performance step-up regulator, two linear-regulator controllers, and high-current operational amplifiers for active-matrix, thin-film transistor (TFT), liquid-crystal displays (LCDs). Also included is a logic-controlled, high-voltage switch with adjustable delay. The step-up DC-DC converter provides the regulated supply voltage for the panel source driver ICs. The converter is a high-frequency (1.2MHz) current-mode regulator with an integrated 14V n-channel MOSFET that allows the use of ultra-small inductors and ceramic capacitors. It provides fast transient response to pulsed loads while achieving efficiencies over 85%.
