Description
- PMP9780.3, Reference Design for Bipolar TFT LCD Supply Using TPS65131-Q1 and Charge Pumps. This reference design details a display power circuit which generates a bipolar voltage rail for source drivers and additional supplies for gate drivers. Charge pumps are used to generate the voltage supply for gate drivers, which makes this design easy to implement. By using only one DC-DC converter to generate four voltage rails and therefore minimizing the amount of inductances, this circuit allows small design size
