TPS40170: compensation phase margin

Part Number:TPS40170

Hi team,

I measured the phase margin and gain margin of the TPS40170 using FRA.

The phase margin value I measured was 65 degrees.

According to the SLVA662(Page. 2), the recommended Phase margins is 45 degrees to 60 degrees.

Does this result afffect the operation?

Regards,

keisuke
