Description The MAX17094 includes a high-performance step-up regulator, a 250mA low-dropout (LDO) linear regulator, a high-speed operational amplifier, a digitally adjustable VCOM calibration device with nonvolatile memory and IC interface, and seven integrated high-voltage level shifters. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications. Request Full Data Sheet The step-up DC-DC converter is a current-mode regulator that provides the regulated supply voltage for panel source driver ICs. The currentmode architecture provides fast-transient responses to pulsed loads typical of source driver loads. The high switching frequency, which is programmable to any frequency between 450kHz to 1.2MHz with a single resistor, allows the use of ultra-small inductors and ceramic capacitors. The step-up regulator's soft-start time is controlled by an internal 10ms digital timer that requires no external components; or if desired, the soft-start time can be adjusted by adding a single external capacitor. The low-voltage LDO linear regulator can provide at least 250mA. The output voltage is accurate within 2%. The high-voltage, level-shifting scan driver is designed to work with panels that incorporate row drivers on the panel glass. Its seven outputs swing from +30V to -10V and can swiftly drive capacitive loads. The high-performance op amp is designed to drive the LCD backplane and features 20MHz bandwidth, 45V/s slew rate, and 150mA output currents. The programmable VCOM calibrator is externally attached to the VCOM amplifier's resistive voltage-divider and sinks a programmable current to adjust the VCOM voltage level. An internal 7-bit digital-to-analog converter (DAC) controls the sink current. The DAC is ratiometric relative to AVDD and is guaranteed monotonic over all operating conditions. The calibrator includes a nonvolatile memory device (IVR) to store the desired VCOM voltage level. The 2-wire IC interface simplifies production equipment. The MAX17094 is available in a 48-pin, 6mm x 6mm TQFN package with a maximum thickness of 0.8mm for thin LCD panels.
