Tool/software:
Hi experts! I'm Yoyo.
My customer Delta have three questions about UCC34141-Q1
1.Since the ENA pin is active high, can I leave it without external components if I don’t need the VIN UVLO function?
2.The PG pin is active low , can I also omit external components for this pin? Or should I consider using UCC34141A-Q1 instead?
3.At the moment I need to simplify the circuit, and these two functions aren’t critical for my design. Do I have to derive a Vbias from a VIN divider to drive these two pins?
