TFT LCD Integrated Power Module for Automotive

The RTQ6749 is an I2C interface programmable power management IC. The IC includes two synchronous boost converters for PAVDD and VGH, one synchronous NAVDD buck-boost, one VGL charge pump, one high performance VCOM with 8-bit Calibrator and one RESET voltage detector. With available in a WQFN-32L 5x5 package, this device is suitable for automotive TFT-LCD panel.

The IC can operate from 2.5V to 5.5V input voltages. High switching frequency operation prevent that the switching noise to interfere AM band. Current-limit functions are provided for all internal- switch converters, and output-fault shutdown protects all converters against output-fault conditions, and output the FAULT signal to communicate with automotive computer. Programmable soft-start functions for all output voltage to limit input inrush current during startup. The recommended junction temperature is -40°C to 150°C, and the ambient temperature is -40°C to 105°C.
