Description
The MPQ5613B is an integrated power supply for automotive LCD TFT bias drivers. The device integrates a configurable, fixed-frequency boost converter (VDDP), a synchronous buck-boost inverter (VDDN), an adjustable positive charge pump output (VGH), and an adjustable negative charge pump output (VGL) for the gate voltages. It also includes a VCOM buffer to minimize the external components. The MPQ5613B is designed to power TFT LCD panels from a regulated 3.3V or 5V supply.
VDDP can output a maximum 9V voltage, VDDN can output a minimum -10.3V negative voltage, VGH can output a maximum 32V voltage, and VGL can output a minimum -15.9V negative voltage.
The I2C interface and configurable power-on sequence for VDDP, VDDN, VGL, and VGH make the IC suitable for different applications. An internal soft-start (SS) function prevents input overload at start-up. Cycle-by-cycle current limiting reduces component stress.
The MPQ5613B is available in a tiny QFN-28 (4mmx5mm) package, and is AEC-Q100 qualified.

APPLICATION
DISPLAY (NAVIGATION, HEADS-UP, CLUSTER)APPLICATIONAutomotive displays — which include the center display, heads-up display (HUD), and gauge instrument cluster — show key information and interactive content to the driver. The center information display is connected to the head unit, and provides navigation and other in-cabin infotainment controls. The automotive HUD and gauge instrument cluster provide easy-to-access information for the driver. Th...
