Part Number: TPS65131 Tool/software: Hi Sir,
My customer use TPS65131 for 4V to +- 5.5V application. (power for LCM module with aroung 20mA current spent). It's +5.5V output looks fine, but -5.5V has 1V switching noise.
Without load:
With load: …
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 Tool/software: My circuit is built using a TPS65131 to output ±15V with a 5V input.(Target current +160mA,-140mA) My circuit is created as shown in figure 8-1(Typical Application) in the data sheet. The values of the compo…
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…
I have only tested a small sample size, but I THINK this has fixed the issue. I will let you know if I encounter the same problem on a larger sample size.
Thanks for your help! - Ben
Part Number: TPS65131 Tool/software: Hi,
I am using TPS65131RGER for +/-12V in my design. When I connect the load negative voltage to going to -18V. without load I am getting proper output.
I have attached the schematic.
Thanks,

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…
