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…
Part Number: TPS65130 Hi Experts,
My customer reported an issue of TPS65130 circuit: occasionally the negative output cannot start up.
The circuit is typical ckt in datasheet. It generate +/-12V output from +5V input. The load current is +/-20mA (MAX…
Part Number: TPS65130 Dear Ti.
I made my own PCB with the following schematic
There are some problem with positive and negative output.
Please see the pictu res below.
(CP and CN stat)
How can i fix this?
Thanks.

Part Number: TPS65130 I have a board using TPS65130 to generate +/-15V from +5.5V input and similar circuit to the one shown in app circuit. A few of TPS65130 have been found to be damaged and checking carefully on the circuit nodes I have found two things…
Hi Jeff,
Yes you are right, OUTN should also be a square wave. So I would suggest you optimize your layout related to OUTN, you can place the inductor and diode near the IC OUTN pin. You can refer to datasheet "11.2 Layout Example".

Part Number: TPS65130 Hello ,
In our application , the VSP and VSN of TPS65130 is connected to a dynamic load under 90HZ.(the TE signal represents the dynamic frequency of the load)
After we disable power-save mode , the overshot of VSP is small , but…
Part Number: TPS65130 Other Parts Discussed in Thread: TPS65120 Hello ,
In the debugging TPS65130 , we found that the VSP(positive voltage) has a drop during start up .
we try to remove C12 and increase C12 to 12pf , this drop cannot be eliminated.
How…
Part Number: TPS65130 Hi , In our a new project , we use TPS65130 for VSP and VSN power rails. Below is our design requirements: VSP : when EN is high , output voltage 5.7V , output max current 0.25A , the ripple less than 20mV ( Vpp value) ;when EN is…
