The RTQ6752-QT is an I2C interface programmable power management IC. The IC includes two synchronous boost converters for PAVDD, one synchronous NAVDD buck-boost, with 8-bit Calibrator and one RESET voltage detector. With available in a WET-WQFN-20L 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.
