TPS63810: Datasheet test setup

Part Number: TPS63810


Tool/software:

Dear Team,

One my customers is struggling reproducing a figure similar to figure 44 from the datasheet evaluating your TPS63810 and generating load steps. They are struggling with the power supply to provide a stable voltage source to the TPS during the load step, without oscillating. Could you help explain the setup TI used to generate these plots? What is the exact circuit under test, especially what input capacitors are fitted, and if possible which power supply we use to supply the DUT?

Thank you,

Daniel Waleniak

  • Hi  Daniel,

    To avoid the oscillation at input during load transient, it is more about the cable connected between power supply and converter, the ESR and ESL of the cable is key to avoid unexpected oscillation.

    Plots in DS are got based on our EVM.
