My customer uses PMP9780 reference design for their application, currently we have three questions as below,
1. Our inductor computation is as below. My application…
Part Number: PMP9780 Other Parts Discussed in Thread: TPS65131-Q1 Dear expert,
Our customers plan to develop design using PMP9780. But their 3.3V input power supply is limited 1A.
How to improve further PMP9780 inrush current?
Best regards,…
Part Number: PMP9780 Other Parts Discussed in Thread: TPS65131 Hi Expert,
My customer is evaluating this reference design PMP9780. They want to get a bigger output current of the charge pump circuit (max 15mA).
Do you have any suggestion about this…
Part Number: TPS65131 Other Parts Discussed in Thread: PMP9780 Hi Team,
Do we have the PMP9780 reference design's SCH and layout in Gerber/Altium Designer format that could share to customer? Or the device's package in Gerber/Altium Designer format…

Part Number: TPS65140-Q1 Other Parts Discussed in Thread: PMP9780 , TPS65131 Dear team,
Could you please help recommend one appropriate device to support below LCD specs? VIN=VDD=3.3V, there are four output voltages as below.
Thanks & Best Regards…
Hello,
Please check out this reference design:
The TPS65131-Q1 with external charge pumps would be a good solution for this requirement.
Best regards, Brigitte
Hello kura,
I do not have data that I can share, for exactly these output voltages, but you might have a look at this reference design, which is close: http://www.ti.com/tool/PMP9780
In addition, if you want to do some tests by yourself, you could…
Hello Kevin,
1) Does this mean that you will only use the CKVx as output and do not connect CKVBx to the panel? What about the corresponding xCSx-channels? I will need to check in the lab if this is possible, but I see doubts as If CPVx is LOW the…
Hello Kevin,
This application requires a bipolar source and gate supplies and we do not have one device that can accomplish that but we do have TPS65131 that can be used with external discrete charge to generate these four rails. Please see TI design…
