Hi Team,

Does UCC28950 has soft-stop feature that gradually decrease PWM duty cycle when VDD happens to drop below UVLO?
I believe it doesn't have but would like to confirm just in case.

Hi Kensuke-san,

I will ask the applications engineer for the UCC28050 to answer this question for you.

Hello Kensuke-san

The short answer to this is 'NO'. There is no soft-stop feature in the UCC28950. If you need one, then you would have to add some external circuitry.
