TPS63000: low power mode disable

Part Number: TPS63000

Hi,

We have a design using TPS63000, but we encounter an issue when low power mode is disabled. VIN is 5V and VOUT 3V3

Output capacitor is 2x47µF + 1x10nF + 1x33pF

Any idea how to avoid this peak on Vout?

Best regards,
Andrés B.

    Hi  Andres,

    Device always try to find a new operating point when mode transition and it will takes some time. that is why some overshot or pull-down will be observed.

    To decrease this overshot, i think we can try with a feedforward cap iin parallel with your up resister of divider.

    Regards
