The TPS65176 provides a simple and economic power supply solution for a wide variety of LCD bias applications. A buck converter generates a logic supply for the timing controller (T-CON) while a boost converter generates the AVDD voltage to power the Source Driver ICs. Two regulated charge pump controllers generate VGON and VGOFF with very few external components to turn on and off the display transistors. The sequencing of the supplies at power on is fully controllable by the user. The TPS65176 also includes various protection mechanisms to ensure the safe operation of the LCD panels.
