The TPS65161 family offers a compact power supply solution to provide all four voltages required by thin-film transistor (TFT) LCD panels. With their high current capabilities, the devices are ideal for large screen monitor panels and LCD TV applications. Compared to the TPS65160 and TPS65160A the TPS65161/A/B family of devices offer increased step-down converter output current. The TPS65161B also offers increased charge pump output current, and a higher undervoltage lockout threshold. The devices can be powered from a 12-V input supply and generate the four main supply voltages required by TFT LCD display panels. Each device comprises a boost converter to generate the source voltage VS, a step-down converter to generate the logic supply V(LOGIC), and regulated positive and negative charge pumps to generate the TFT bias voltages VGH and VGL.
