Part Number: TPS65131 Hello,
I am contacting you regarding your component TPS65131.
I would like to understand and optimize the adjustment of the corrector in order to increase the stability margins of the converter. I saw on the datasheet that there…
Part Number: TPS65131-Q1 Hi,
We are using part TPS65131RGER in our design.
Input = 3.3V
o/p +15 and -15 , both loads 75mA
How we can determine the power across the device?
We need to calculate temperature rise of the part.
Regards,
AVM
Part Number: TPS65131TPS65131RGE - Can a TI engineer please give us some clue as to why our -9V is ~0.8V? We've experimented with a number of values of R81 with no effect.
Adding layout if it offers any clues. We are completely stumped. Beyond…

Part Number: TPS65131 I have also removed C118. Also, the chip is making a clicking noise.
I'm trying to get -9V and +9V out. Instead my +9V is 10.2V, my -9V is not stable, around -12 to -14 and always moving.
I have also removed R83 and R84 to…
Part Number: TPS65131-Q1 Hi,
Here is the datasheet for the part:
TPS65131-Q1 Positive- and Negative-Output DC-DC Converter datasheet (Rev. E)
On page 23, the datasheet shows several efficiency graphs. My application goes up to 80C. Typically, the efficiency…
Part Number: TPS65131 Hi,
my customer is using TPS65131TRGERQ1 in an industrial application and due to supply situation is evaluating to use TPS65131RGER instead.
85degC is ok for the application, two open questions:
1. Electrical spec seem the same, therefore…
