DescriptionThe TPS65150-Q1 is an integrated power-supply for automotive LCD applications. The deviceintegrates a boost converter for the source voltage and two regulated adjustable charge pumpdrivers for the gate voltages. For reduced external cost, improved picture quality and reducedimage sticking, the device includes a VCOM buffer and a gate-voltage shaping function.
The device is designed to operate from a supply voltage of 1.8 V to 6 V making it idealfor automotive LCD applications using a fixed 3.3 V or 5 V input-voltage rail.
Adjustable power-on sequencing for VGL and VGH allow the device to be optimized for avariety of displays.
For protection from system malfunction, the TPS65150-Q1 integrates an adjustable shutdownlatch feature. The device monitors the outputs (V(VS),V(VGL), V(VGH)); and, as soon as one of the outputsfalls below its power-good threshold for longer than the adjustable fault delay time, the deviceenters shutdown.
