  • TPS65400: Device startup error

    TI Thinks Resolved
    Part Number: TPS65400 Tool/software: Hello, My customer is testing the TPS65400 operation on a board they designed as shown in the circuit below. TI_PMIC_TPS65400RGZT.pdf . When they measured VDDA, VDDG, and VDDD after inputting VIN 12V and CE high…

  • TPS65400: SW2 output regulation error

    TI Thinks Resolved
    Part Number: TPS65400 Tool/software: Hello, I am triyng to use TPS65400 for generating 4 indipendent voltages, each one with different regulation; in general Ioutmax = 0.3A and Vout = 7...9V. The control of the Ic is made with I2C protocol. The schematic…
