TPS53355: Circuit design review

Part Number: TPS53355

Hello

One of my clients is using the TPS53355 for this project.

It seems to me that it was applied with the right design values.

Could you please take one more review?

I will deliver the corresponding schematic file.

  • The ripple injection components seem unusual. Please check the datasheet. You are showing "Compensation networks". What are they for?
  • Hello

    The following changes have been made regarding "ripple injection".
    (Datasheet and WEBENCH Note)
    R620 2.05 ohm -> 49.9 Kohm
    C842 100nF -> 22nF
    C845 100pF -> 1nF

    R432 2.05 ohm -> 57.6 Kohm
    C571 100nF -> 22nF
    C574 100pF -> 1nF

    R447 2.05 ohm -> 49.9 Kohm
    C695 100nF -> 22nF
    C689 100pF -> 1nF

    Do you think the OUTPUT CAP is too big?

    Currently, ENABLE is designed to be controlled externally.

    It is used for repeater equipment.
