  • TPS65131: TPS65131 vs TPS65131-Q1

    TI Thinks Resolved
    Part Number: TPS65131 Hi, my customer is using TPS65131TRGERQ1 in an industrial application and due to supply situation is evaluating to use TPS65131RGER instead. 85degC is ok for the application, two open questions: 1. Electrical spec seem the same, therefore…

  • TPS65131: Can't get proper outputs, startup failure?

    Part Number: TPS65131 I have also removed C118. Also, the chip is making a clicking noise. I'm trying to get -9V and +9V out. Instead my +9V is 10.2V, my -9V is not stable, around -12 to -14 and always moving. I have also removed R83 and R84 to…

    Part Number: TPS65131-Q1 Hi, Here is the datasheet for the part: TPS65131-Q1 Positive- and Negative-Output DC-DC Converter datasheet (Rev. E) On page 23, the datasheet shows several efficiency graphs. My application goes up to 80C. Typically, the efficiency…

  • TPS65131: Component does not work accordingly

    Part Number: TPS65131 For our PCB we are using the TPS65131, however it does not work the way we expect it to. As a starter our Vpos is at a steady 10V instead of 15V And Vneg is either 0V or it jumps to -7 V and then slowly goes back to 0V and that jumps…
