Part Number: TPS552882
Other Parts Discussed in Thread: TPS55288

Hello:

Would you think  Fig 6.3 , 6-4, 6-5 & 6-6 in the document

SLVSF01B – NOVEMBER 2018 – REVISED DECEMBER 2020

one has to ignore those Vin -vout plots which do not apply when vout>vin for a buck?

I-appreciate any clarification of this matter.

    Hi Robin,

    Thanks for reaching out on E2E.

    The TPS55288 is a synchronous four-switch buck-boost converter capable of regulating the output voltage at, above, or below the input voltage. So all the plots in Fig 6-3, 6-4, 6-5, 6-6 are real application.

    Regards,

    Bryce
