TPS54328: TPS54328 question about max output voltage range?

Part Number: TPS54328

Dear support member,

My customer used TPS54328.

I have a question.

Why the max output voltage range is regulated at 7V?

Best regard.
Bob Lee.


    The TPS54328 uses TI's D-CAP2 control architecture which combines the benefits of Constant On-time Control with an internally generated ramp that allows the COT control loop to be stabilized with no requirement for ESR on the output, allowing it to use all types of output capacitors, including low ESR ceramic capacitors.  The internal ramp is derived from the switching node and maintains a DC average voltage equal to the output voltage.  For reliable operation, that DC average voltage must be maintained below 7V, limiting the output voltage to no more than 7V.

  • Dear Peter James Miller,

    Thank you very much for your answer.

    I reply my customer your answer.

    I will feddback it.

    Best regard.
