MAX17075 pdf datasheet (Boost

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 currentmode
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
+85°C temperature range.
