Hi
Hi Yokota-san,
Thanks for bringing this to our notice.
You were seeing the issue because the Minimum on time of the device TPS54719 was being violated at 1.9 MHz at 5.5V Vin,0.9V Vout,3.5A Iout condition.
We have made changes to frequency ceiling(maximum switching frequency) calculations and now it is working fine. For the above input-output conditions, the maximum switching frequency is now limited to 1.63 MHz taking minimum on time into account.
We will let you know once the changes are released to www.ti.com
Best Regards,
Vishwanath
