Part Number: TPS65131-Q1 Other Parts Discussed in Thread: TPS65131 Hi, I am inquiring about the voltage step of the positive voltage that occurs at start up of the TPS65131.
Currently we have it set to 10V.
On voltage start up, +10V reaches 10V with a…
Part Number: TPS65131-Q1 I checked the switching frequency of the TPS65131Q1. The switching waveform is distorted as shown below. It doesn't look like a normal switching waveform, can you explain why it looks like this?
(+10V below switching waveform…
Part Number: TPS65131 Dears,
Customer use the tps65131,Vin is 3.3V,output is ±15V,now found the -15V is not stabilize,pls kindly help to check it.
The schematic pls find the attachfile.
Thanks

Part Number: TPS65131 Generates +5V → +15V using TPS65131RGER.
I used 7pF for the VPOS capacitor, but the ripple voltage was 1.58V, which was high. When I changed it to 220pF, it improved to about 0.237V.
If I use 220pF, it will be different from…
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 Other Parts Discussed in Thread: TPS65150-Q1 Hi Sir,
The customer asked that TPS65131-Q1 and TPS65150-Q1 both devices if have passed the below AEC-Q100 Qualified test items? or only have passed some test items?
Both devices' D…
Part Number: TPS65131 Dear team,
My customer has abnormal output issue on TPS65131. the expected output is 15V but the result is only 5V.
- Input voltage :5V.
- Below is customer schematic.
Below is soldering X-ray image. As you can see below, there…
Hi Gareth,
1. Do you have load current and inductor current waveforms?
2. You can try CN capacitance with 10nF as well.
3. Will the IC work if the VPOS and VNEG are ramping up without load connected, and after ramping, connecting the load back?

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
