MAX8758 General Description


The MAX8758 includes a high-performance step-up regulator, a high-speed operational amplifier, and a ogiccontrolled, high-voltage switch-control block with programmable delay. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications.

The step-up DC-DC regulator provides the regulated supply voltage for the panel source driver ICs. The converter is a high-frequency (640kHz/1.2MHz), current-mode regulator with an integrated 14V n-channel power MOSFET. The high-switching frequency allows the use of ultra-small inductors and ceramic capacitors. The current-mode control architecture provides fast transient response to pulsed loads. The regulator achieves efficiencies over 85% by  ootstrapping the supply rail of the internal gate driver from the step-up regulator output. The step-up regulator features undervoltage lockout (UVLO), soft-start, and internal current limit. The high-current operational amplifier is designed to drive the LCD backplane (VCOM). The amplifier features high output current (±150mA), fast slew rate (7.5V/s), wide bandwidth (12MHz), and rail-to-rail inputs and outputs.

The MAX8758 is available in a 24-pin, 4mm x 4mm, thin QFN package with a maximum thickness of 0.8mm for ultra-thin LCD panels. The device operates over the -40°C to +85°C temperature range.
