The MAX8798ETX+ from Analog Devices is a high-performance power management IC optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications. It features an integrated step-up DC-DC converter that provides regulated supply voltage for panel source driver ICs, operating with a switching frequency that allows for small inductors and capacitors.
The device also includes a high-speed operational amplifier designed to drive the LCD backplane (VCOM), offering ±150mA output current and a 20MHz bandwidth. A digitally adjustable VCOM calibration device with nonvolatile memory and an I2C interface are included for precise voltage level adjustment and simplified panel connections.
Additionally, 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 efficiently. The IC is available in a 36-pin thin QFN package with a maximum thickness of 0.8mm, suitable for ultra-thin LCD panels.
Key electrical specifications include an input supply voltage range of 1.8V to 5.5V and a VDD input voltage range of 1.8V to 4.0V. The operating temperature range is -40°C to 85°C. The device is surface-mountable and comes in a 36-TQFN package.
