The MAX17075 includes a high-voltage boost regulator,one high-current operational amplifier, two regulated charge pumps, and one MLG block for gate-driver supply modulation.The step-up DC-DC converter is a 1.2MHz current-mode boost regulator with a built-in power MOSFET. It provides fast load-transient response to pulsed loads while producing efficiencies over 85%. The built-in 160mΩ (typ) power MOSFET allows output voltages as high as 18V boosted from inputs ranging from 2.5V to 5.5V. A built-in 7-bit digital soft-start function controls startup inrush currents.The gate-on and gate-off charge pumps provide regulated TFT gate-on and gate-off supplies. Both output voltages can be adjusted with external resistive voltage-dividers.The operational amplifier, typically used to drive the LCD backplane (VCOM), features high-output short-circuit current (±500mA), fast slew-rate (45V/µs), wide bandwidth (20MHz), and rail-to-rail outputs.The MAX17075 is available in a 24-pin thin QFN package with 0.5mm lead spacing. The package is a square (4mm x 4mm) with a maximum thickness of 0.8mm for ultra-thin LCD design. It operates over the -40°C to +105°C temperature range.ApplicationsLCD Monitor PanelsLCD TVsNotebook Computer Displays
