Part Number: TPS65131-Q1 Other Parts Discussed in Thread: OPA2891 , OPA1633 , , TPS7A39 Tool/software: Can we use TPS65131-Q1 alone to power two OPA2891 and four OPA1633? Can we use 5V input and +/- 15V outputs from TPS65131-Q1 directly, or is it better to…
Part Number: TPS65131-Q1 Tool/software: Hi Expert,
Have a nice day! I have question need your professional support:
How to calculate the Total output dc accuracy=3%?
It only has relationship with the device, have no relationship with the feedback resister…
Part Number: TPS65131-Q1 Tool/software: Hi, TI expert.
A customer has requested a review of the TPS65131TRGERQ1 schematic.
- Application : Car Display AVN
Designed for TDDI power (VSP/VSN,VGH./VGL).

Part Number: TPS65131-Q1 Other Parts Discussed in Thread: LM27762 , TPS65131 Tool/software: We need +/- 2.5V at a low current of around 20-30mA.
Will this IC support +2.5V? I noticed that the minimum Vpos is 3.2V.
Also, the efficiency appears quite low…
Part Number: TPS65131-Q1 Other Parts Discussed in Thread: TPS65131 Tool/software: Dear TI Engineer,
During our testing we found that when the input 3.6V power supply (PERIF_SWR3V6) is boosted by TPS65131 to a 5.5V output (OLED-AVDD5V5), there is a sho…
Part Number: TPS65131-Q1 Tool/software: Hello, everyone.
I would like to use the TPS65131-Q1 to create a circuit that inputs +5V and outputs -9V (output current 600mA(Typ.)).
Positive power supply output is not necessary this time.
I created the circuit…
Part Number: TPS65131-Q1 Tool/software: I want to use only a negative power supply. In this case, ENP: Fixed to L INP/VPOS/FBP/CP: Open Will this be okay?
Part Number: TPS65131-Q1 Tool/software: I want to create -2.5V from 5V. An output current of 20mA is sufficient. If the current consumption is small, when calculating the standard inductor value, it comes out to a very large value of 130uH.
Would it be…
Part Number: TPS65131-Q1 Other Parts Discussed in Thread: OPA1612 , Hi there,
I'm after a split rail supply to power 8 x OPA1612 op amps in a high quality preamplifier. I'm limited to using a single DC supply to the board. I have put together a schematic…
Part Number: TPS65131-Q1 Other Parts Discussed in Thread: BUF634A Hi
I'm looking for a solution to create a split rail supply for the BUF634A buffer.
Requirements
Vin: 24V
Vout: 8-10V (+/-)
Iout: 500mA OR 2.5A (driving 5 buffers, so separate DCDC…
