TPS43060: VIN Biased from VOUT

Part Number: TPS43060

Tool/software:

Hi support team,
Is the configuration in Figure 2 applicable to the TPS43060?

  • Hello Dice-K,

    Thanks for reaching out to us.

    Yes, the same concept can also be used for the TPS43060.
    Both controllers can be supplied by their own boosted output voltage, as long as the peak output voltage remains below 38V.
    Please consider some margin for overshoots for example in case of a load dump.

    Also, you need to make sure that the input voltage for the power stage will not drop below a value where it can no longer boosted to the expected output voltage
    (either because the input current will become too high or because the duty cycle will become too big.
    Maybe, for this purpose use a voltage divider on the UVLO pin and configure it accordingly.
