Part Number: TPS65130 Tool/software: I have made a PCB based on the TPS65130 for an adjustable positive and negative power supply. After installing the components and testing the PCB I am getting strange results.
When DAQ output = 4.93 Vneg= 3.3v, 2…
Part Number: TPS65130 Tool/software: Hi Team,
customer feedback the TPS65130 drains high current while no loading.
They needs to control the ENP signal by MCU.
If tied ENP and PSP then will become normal.
Attached waveform for ENP and current…
Part Number: TPS65130 Tool/software: Hi Team,
I'm designing a DC/DC converter that uses 5V DC directly from the USB VBUS and is meant to output +/-15V.
The problem I'm having is that I have 0V at the output capactiors of the V_POS (+15V) and -5V…
Part Number: TPS65130 Hi team,
We are considering using the TPS65130 for only the negative output. In the circuit diagram shown in section 8.2 “Typical Application” of the datasheet, is it correct to assume that the following peripheral components can…
Part Number: TPS65130 Tool/software: Hi AE,
Currently, we plan to design an output of +12.5V/1mA and -12.5V/1mA.
Since the specification requires a minimum current of 700mA, what risks might occur if we operate below 1mA?
We would like to consult…

Part Number: TPS65130 Other Parts Discussed in Thread: TPS65132 Hi experts,
In our application, we meet one surge issue during power-on stage with TPS65130, the sch. is attached, we capture the power-on voltage and current of TPS65130's input (USB5V_ISO…
Part Number: TPS65130 Hi, I designed an ordered my board and have tested several of them now. It is for a smart watch and I'm trying to power my AMOLED screen so I need +4.6v and -2.4v output. The +4.6v output works as expected, but instead of getting…
Part Number: TPS65130 Tool/software: Hi,
Please help check our schematic diagram that we have no negative voltage output for TPS65130RGER;
We use the 2Kohm load and the p ositive pressure output is +7V, and we consider the negative voltage output…
Part Number: TPS65130 Hi,
We use the TPS65130 for the 5VDC to +/-14V design, and now, there is failure rate is about 1/20 that -14VDC output voltage is only about output -3VDC when the power on, the failure rate is about 1/20;
The below is the sahematic…
