Hi,

which one should i trust, excel sheet or datasheet? i did go with the datasheet formula, for now...

TPS55289-CALCULATION-TOOL-V1.0.xlsx suggests 8.1kOhm for 2.2MHz

Datasheet formula suggests 8.4kOhm for 2.2MHz

    Hi Cor Los,

    Thank you for reaching out. Please refer to datasheet.

    Excel tool use different fitting formula with datasheet, the result is similar but datasheet is more accurate. We will update excel tool later.

    Regards,
