MAX8798ETX Description

Short technical summary and product information.

The Analog Devices MAX8798ETX is a versatile integrated circuit designed for Thin-Film Transistor (TFT) Liquid-Crystal Display (LCD) applications. It features a high-performance step-up DC-DC converter that provides regulated supply voltage for panel source driver ICs, operating with an input voltage range of 1.8V to 5.5V and a VDD input range of 1.8V to 4.0V. The regulator utilizes a 1.2MHz current-mode control architecture for fast transient response and supports ultra-small inductors and ceramic capacitors.

This device also includes a high-speed operational amplifier optimized for driving the LCD backplane (VCOM), offering ±150mA output current, a 45V/µs slew rate, and a 20MHz bandwidth. A digitally adjustable VCOM calibration device with nonvolatile memory and an I2C interface is included for precise VCOM output voltage adjustment. Furthermore, the MAX8798ETX incorporates a high-voltage, level-shifting scan driver with three outputs capable of swinging between +45V and -25V, designed to drive TFT panel gate drivers.

The MAX8798ETX is available in a compact 36-pin, thin QFN package with a maximum thickness of 0.8mm, making it suitable for ultra-thin LCD panel designs. Its integrated features and optimized performance make it an ideal solution for notebook computer displays and LCD monitor panels.
