Description

The MAX1516A/MAX1517A/MAX1518A include 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%. The gate-on and gate-off linear-regulator controllers provide regulated TFT gate-on and gate-off supplies, using external charge pumps attached to the switching node. The MAX1518A includes five high-performance operational amplifiers, the MAX1517A includes three, and the MAX1516A includes one operational amplifier. These amplifiers are designed to drive the LCD backplane (VCOM) and/or the gamma-correction divider string. The devices feature high output current ±150mA), fast slew rate (13V/µs), wide bandwidth (12MHz), and rail-to-rail inputs and outputs. The MAX1516A/MAX1517A/MAX1518A are available in 32-pin thin QFN packages with a maximum thickness of 0.8mm for ultra-thin LCD panels.
