Part Number: TPS65131 The recommended layout in the datasheet is quite a bit different from that in the EVM. It appears the EVM was focused on creating the smallest possible footprint using 0402 resistors and smaller inductors. Was this for performance…
Part Number: TPS65131 Hi sir,
Customer wants to use TPS65131-Q1 to generate a +/-12V or +/-15V output.
According to datasheet, if customer input 3.3V to TPS65131, output +/-12V or +/-15V with 0.4A~0.8A load. Is this application good?
Thanks a lot…

Part Number: TPS65131 Reviewing the datasheet for the TPS65131 part, it appears PGND, AGND and PP are all connected to the same ground plane, although the schematic provided in the TPS65131EVM-839 eval board shows a separation of AGND (for support components…
Part Number: TPS65131
I drew the circuit diagram according to the official recommendation . Boosted the battery or VBUS5V to ±5V through TPS65131.
After I applied the patch, when I actually measured, the positive voltage output was normal, but the…
Part Number: TPS65131-Q1 Dear Engineer,
Can you help check the schematic diagram of TPS65131-Q1? The schematic diagram is not convenient to publish on the forum. Can I contact you via email? Thank you!
Part Number: TPS65131 Hi team,
Cusotmer use TPS65131 in their system.
Design as follow, they change the PSN, PSP to GND, put the chip into PWM mode.
During the start up, they find the negatvie output get large overshot. Could you help check why…
Part Number: TPS65131-Q1 Other Parts Discussed in Thread: TPS65131 We are currently investigating the inrush current characteristics of the ICs used in our product in response to a request from HKMC. To establish the specification criteria for evaluating…
Part Number: TPS65131 Tool/software: Hello TI team,
My requirements are:
Input Voltage is 16V-30V or 26 V.
Output voltage of +15V and - 15V with very low noise at 500mA output current. (Noise should be less than 2 nV from frequency of 10 Hz to 30…
Part Number: TPS65131 Hi,
I made a design for a test device for our DSPs.
It has to generate +-15V from 5V from a USB connector.
But when connected it only produces:
+15 is only +1,5V.
-15V is only 0V.
I'm looking for a bit of help getting…
