1 / 31 page General Description The MAX8795A includes a high-performance step-up regulator, two linear-regulator controllers, and five 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 con- verter is a high-frequency (1.2MHz) current-mode regu- lator with an integrated 20V 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 MAX8795A includes five high-performance operational amplifiers. These amplifiers are designed to drive the LCD backplane (VCOM) and/or the gamma- correction divider string. The device features high out- put current (±130mA), fast slew rate (45V/µs), wide bandwidth (20MHz), and rail-to-rail inputs and outputs. The MAX8795A is available in a lead-free, 32-pin, thin QFN package with a maximum thickness of 0.8mm for ultra-thin LCD panels, as well as in a 32-pin LQFP package with 0.8mm pin pitch.
