The TPS65163 integrates a boost converter, buck converter, reset generator, two charge pump controllers and a nine-channel level shifter in a single device.

In typical display panel applications, the boost converter generates the display panel source voltage, VS; the buck converter generates the system logic supply, VLOGIC; and the two charge pump controllers regulate the external charge pumps generating the display transistors’ on and off supplies, VGH and VGL.

The level shifters transform the logic-level control signals generated by the display timing controller into the high-level signals needed by the LCD panel. The nine level-shifter channels are organized in two groups, each with its own positive supply voltage (VGH). Each channel uses a low-impedance output stage to achieve fast rise and fall times, even when driving the capacitive loads present in LCD applications. Channels 1 to 6 also support gate voltage shaping.

The TPS65163 also provides a reset circuit that monitors the buck converter output (VLOGIC) and generates a reset signal for the timing controller during power up and power down.

A control signal can also be generated to control an external MOSFET isolation switch located between the output of the boost converter and the display panel.
