  • RE: TPS65131: TPS65131

    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…

  • TPS65131: Chip application problem

    TI Thinks Resolved
    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…

  • TPS65131: TPS65131

    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

  • RE: TPS65131: How to protect LDOs /Upstream TPS65131 during reverse polarity/reverse current

    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. BR Patrick

  • RE: TPS65131: VNEG not regulated at no-load, but regulated at load

    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. BR Patrick

  • TPS65131: Inductor value calculations

    Part Number: TPS65131 Other Parts Discussed in Thread: LM3310 , LM2700 , Tool/software: Vin = 3.3 Vpos = 15 Vneg = -15 Ipos = 0.1 Ineg = 0.1 Using the equations in the datasheet I get: I_Lp = 710mA I_Ln = 870mA L1 = 14uH L2 = 12uH However, using the Webench…

  • TPS65131: TPS

    Part Number: TPS65131 Tool/software: Hi, I want to converter my battery voltage which varies from 18V to 25.2 V to dual polarity voltages (adjustable) from +/- 25V to +/- 48V with output current of at least 5A. Input Voltage: 18 to 30V DC Output 1:…
