UCC2808-1: High Power DC/DC regulator design help

James Yount
Prodigy 30 points
Part Number: UCC2808-1
Other Parts Discussed in Thread: LM5045, LM5046, UCC29002

I would like to use the UCC2808-1 push pull design as described in this webbench power design: webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=05EB8E641095661F

I'm having trouble picking out an appropriate transformer.  Can someone help me design a high power (1kw) DC/DC buck circuit?  I need resources and assistance, please.  Is there a design available that I can reference?

    Hi James,

    For this spec, I'd like to recommend you use full bridge topology, such as device LM5045, LM5046.

    If you prefer to use a buck converter, here are reference designs for your reference, you can find them on TI.com.

    Regards,

    I don't see a solution here for 36V output at 1kW (900W typical).  I would consider using bucks in parallel if I can get the appropriate power and there are application notes for how to wire them in parallel appropriately to share the load.

    Hi James,

    Sorry, there is no available reference design with your requested specs, but I think you can still refer these reference designs.

    Besides, load share controller UCC29002 (UCC29002-1, UCC29002-2) is recommended to parallel multiple independent power supplies.

    Regards,
