Hi Keisuke-san,

Device TPS54325 has maximum duty cycle limit of 70%.

On discussion with product expert we have extended the maximum duty cycle of device to 80%.With this change design gets created for the condition mentioned above.

The change is currently in our internal servers and will be available on ti.com tentatively by end of next week.

We shall keep you updated on the same.

For an immediate reference kindly refer the attached design report for the condition mentioned above.1425.TPS54325.pdf
