UCC28780: HOW TO DISABLE UCC28780 FOR THE UVLO/ENABLE FUNCTION OF DC DC CONVERTER

Hi Sir:

we try to use UCC28780 in a DC-DC converter, while we need precise UVLO and ENABLE function; we can build those functionS with open collector output, while we don't know where to connect it to UCC28780 so it can work; can you please help to check this?

thanks a lot;
