UCC24612: Low Side vs High Side

Part Number: UCC24612

Hi,

Is there any significant performance difference between low and high side configuration using UCC24612?

Best regards,

  • Hi, Ali:

    The SR MOSFET power consumption would be the same no matter high or low side configuration. Some people mention it can get better EMI/RFI performance when they connect SR MOSFET as high side configuration. The interesting thing is, I also heard some designers mention EMI/RFI is lower when they connect SR MOSFET as low side configuration.  So it is hard to say which one is better, the performance is still based on whole system design I think.  

    Therefore, since the power consumption would be the same, you may choose high side or low side configuration according to your experience and your system. 

    Thanks.
