Hi Sumeet,
Please see the linked app note for creating a split rail supply from a wide input voltage buck regulator: https://www.ti.com/lit/an/slva369a/slva369a.pdf?ts=1743549763159&ref_url=https%253A%252F%252Fwww.google.com%252F
This provides a method…
Part Number: TPS65131 Tool/software: I would like to ask about the TPS65131 component. The measured FBP voltage is not within the range specified in the datasheet. One is around 1.36V and the other is 1.42V. The Vref voltage is 1.176V, which is also…
Part Number: TPS65131 Tool/software: My circuit was built using a TPS65131 to output ±15V at 5V input (target current +200mA, -200mA).
Dynamic response amplitude is large, how can it be reduced? EP15V动态响应问题20241118 .pdf
Hi Abigail,
Is the reverse current a continuous current or a pulse current? If it is a continuous reverse current, what would be the amplitude? If it is a current pulse, please also provide the pulse width together with the amplitude.

Part Number: TPS65131 Tool/software: Hello supporter,
I need some advice to get a stable operation on negative output of TPS65131.
Positive output is fine but negative output has fluctuation (seems like resonant) from time to time..
Target negative…
Part Number: TPS65131 Tool/software: Hi,
My customer is looking to see what TI recommends doing to safeguard the TPS65131 from reverse current and reverse polarity from upstream LDOs. The example circuit is below:

Hi Adam,
It is ok to remove this cap, it is used to adjust the loop performance. So if remove it will help to increase the stability, that's fine.
