UCC24650: Putting flyback output diode on high side when using UCC24650?

Part Number: UCC24650

After review UCC24650, it is good IC to wake up PSR flyback controller for output dynamic response. As we know, putting output rectifier diode on high side is better for EMI. My question is whether we can put output rectifier diode on high side when using UCC24650.


  • David,
    Thanks for your question here. UCC24650 has only been validated in a use case as a low side rectifier. As we have not validated it in system as high side and I can see that it would require additional circuitry I would not recommend use as high side.
