110VDC/AC to 24VDC

Other Parts Discussed in Thread: UCC25600, UCC28951, UCC2897A, LM5036

Hi sir,

I am looking for a 110 VDC/ 110VAC to 24VDC convertor solution. Input can be either AC or DC and is flow from same input connector (same pins). And the required maximum output current is 9A.

Please provide the available solutions from TI. Thanks.

Regards,

LYS

    Hi user5013275,
    Please can you advise if you require the output to be isolated from the input?
    What is the range of input voltage over which you need to be able to deliver full output power.
    Do you have any hold-up requirement?
    Thanks

    Hi Joe Leisten,

    Thanks for your reply,  my design need isolated output. Input voltage range is 100-135v.

    Please suggest some solutions, thanks.

    Regards,

    Hi user5013275,
    For this voltage range I would suggest one of the following topologies as being most suitable:
    Half-Bridge LLC (UCC25600, UCC25630x - pick one without X-cap discharge to support DC input)
    Phase-shifted full-bridge (UCC28951)
    Active Clamp Forward (UCC2897A and others)
    Hard switched half-bridge (LM5036 and others - you will need external HS drivers for this voltage range)
    Two switch Forward topology.
    All of the above topologies should be able to deliver the specification you require.
    If you settle on which topology you prefer I may be able to supply details of a design that comes fairly close to your requirement from our design library.
    Thanks
