Part Number: UCC28780

Hi;

      The customer wants to make a small volume adapter with output power of 180W,

and apply GaN technology. It is recommended whether the application program is suitable.

thank you

  • We need to know your design specs such as input and output voltages, efficiency target. Only it is difficult to make suggestion only based on 180W output.

    Hi Hong:

           Sorry,I didn't give you enough information before

           Input:100V~240VAC;

           Output: 19.5VDC/9.3A     CV model

           Pout:180W;

    The client needs the adapter size to be as small as possible,No efficiency requirements have been put forward, but the higher

    the better.Because it improves the temperature of the device;

  • In reply to Tony xiong:

    For 180W rated power, does your specs require PFC in front? If so, I would think LLC may be better with the LLC controller UCC25640x.

    A little bit push on active clamp flyback but it is ok to go with UCC28780 with GaN.
