  • RE: TPS65131: Customer wants to use TPS65131 to power op-amps looking for advice to minimize noise

    Hi David, I'm not sure TPS65131 can do that, in my previous test, the ripple is about mV level. BR Patrick

  • TPS65131: Cannot get negative output -9V

    TI Thinks Resolved
    Part Number: TPS65131 TPS65131RGE - Can a TI engineer please give us some clue as to why our -9V is ~0.8V? We've experimented with a number of values of R81 with no effect. Adding layout if it offers any clues. We are completely stumped. Beyond…

    Hi Sam, We don't have solutions to cover such current spec now. BR Patrick

  • TPS65131-Q1: Efficiency at High Temperature

    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: 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…
