Dear TI people,
Regarding the parameters tON(min) and tDMAG(min).
For the UCC28720 a tON(min) specification is given of 300 ns and tDMAG(min) of 1.2 us.
My first question is: Does the calculated value for tON(min) need to be higher or lower than the 300 ns?
My second question is: Does the calculated value for tDMAG(min) need to be higher or lower than the 1.2 us?
I think the answer would be applicable for the other UCC287XX devices as well.
Furthermore I would really appreciate to receive an answer to my earlier question with the following title: “Apply UCC28720 for 1W 5V isolated flyback from 230 AC mains”
My follow up message had some very basic understanding questions; I still hope to get an answer about.
