I've a new design using the TPS56121. Vin is 12V and Vout is 1.15V. I am seeing excessive over and under shoot on the rising and falling SW pulse. I've followed the web bench design. And used the recommended devices. I've not put a heavy load on the regulator yet (max 1A).
Is there a minimum load for regulation?
Is there a minimum load requirement?
What is the minimum SW pulse width?
I am using this to drive core voltage on a new ASIC reference design. Please contact me internally via email if possible.
Thanks,
Kevin
