Hello guys,
One of my customers is considering using UCC28742 for their next flyback power supply.
At this moment, they have the following question.
Could you please give me your reply?
Q.
We don't need to isolate between primary and secondary side.
So we want to use UCC28742 without opto-coupler.
Is it no problem?
Also if you have any reference schematic for no opto-coupler case, could you please send me it?
Your reply would be much appreciated.
Best regards,
Kazuya.
Hi Nakai-san,
Yes. PMP30545 is an example of how you can do this.
I hope this answers your question.
