The input supply voltage range of the MAX8739 is from 1.
8V to 5.
5V.
The device also includes a logic-controlled, high-voltage switch with adjustable delay.
The step-up DC-DC converter provides the regulated www.

com supply voltage for the panel source driver ICs.
The converter is a high-frequency (600kHz/1.
2MHz) currentmode 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 two high-performance operational 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 (7.
5V/µs), wide bandwidth (12MHz), and rail-to-rail inputs and outputs.
The MAX8739 is available in a 20-pin, 5mm × 5mm thin QFN package with a maximum thickness of 0.
8mm for ultra-thin LCD panels.
