Reference Design: Bipolar TFT LCD Supply Using TPS65131-Q1 and Charge Pumps
Description
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.
Features
- Complete power supply solution for TFT LCD display bias4 output voltage railsLow quiescent current less than 0.5 mALoad regulation less than 2% on all railsAutomotive qualified components
