<!-- Paste General Description -->The RTQ6749 is a programmable power management IC with an I<SUP>2</SUP>C interface, designed for automotive TFT-LCD panel applications. It integrates two synchronous boost converters for PAVDD and VGH, a synchronous NAVDD buck-boost converter, a VGL charge pump, a high-performance VCOM with 8-bit calibration, and a RESET voltage detector. The device is available in a compact WQFN-32L 5x5 package.The RTQ6749 operates from a 2.5V to 5.5V input voltage range. Its high switching frequency minimizes interference with the AM radio band. Comprehensive protection features include overcurrent protection for all internal-switch converters and output-fault shutdown, which protects all converters against output-fault and asserts a FAULT signal for communication with automotive systems. Programmable soft-start functions for all output voltages help limit input inrush current during startup. The recommended junction temperature is -40°C to 150°C, and the recommended ambient temperature is -40°C to 105°C.
