File Size : 116 KB Manufacturer:Sipex Description:The MAX8758 includes a high-performance step-up regu- lator, a high-speed operational amplifier, and a logic- controlled, high-voltage switch-control block with pro- grammable delay. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications. The step-up DC-DC regulator provides the regulated sup- ply voltage for the panel source driver ICs. The converter is a high-frequency (640kHz/1.2MHz), current-mode regu- lator 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 con- trol architecture provides fast transient response to pulsed loads. The regulator achieves efficiencies over 85% by bootstrapping 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/µs), 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 -40C to +85C temperature range.
