MAX17010 Internal-Switch Boost Regulator with Integrated High-Voltage Level Shifter and Op Amp

Description

The MAX17010 contains a high-performance step-up switching regulator, a high-speed operational amplifier (op amp), and a high-voltage level-shifting scan driver. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications.

The step-up DC-DC converter provides the regulated supply voltage for the panel-source driver ICs. The converter is a 1.2MHz current-mode regulator with an integrated 20V 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 step-up regulator features undervoltage lockout (UVLO), soft-start, and internal current limit. The high-current op amp is designed to drive the LCD backplane (VCOM). The amplifier features high output current (±150mA), fast slew rate (45V/µs), wide bandwidth (20MHz), and rail-to-rail inputs and outputs.

The high-voltage, level-shifting scan driver is designed to work with panels that incorporate row drivers on the panel glass. Its eight outputs swing from +30V (max) to -10V and can swiftly drive capacitive loads.

The MAX17010 is available in a 40-pin 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.
