Other Parts Discussed in Thread: UCC28730

Hi team,

My customer would like to us know if UCC28730-Q1 can be used as HV redundancy flyback for input range from 40V to 880V?

Also can this flyback controller be configured for multiple secondary output windings? My customer application requires 3 or 5 secondary output.

Thanks,

Scarlett

Hi, Scarlett:

Thanks for asking.

UCC28730-Q1 can be used as 40VDC-880VDC. It can support multi-output applications.

May I know what's the output specification?

Regards,

Wesley

Hi Wesley,

Each secondary output winding should supply ~24V/0.1A, three or six secondary output windings per different project requirements.

Do you have similar reference design?

Thanks

Scarlett

Hi, Scarlett:

Sorry we have no reference both meet 800Vdc and 24V multioutput.

For Multi-output of UCC28730, TIND-01650 would be a reference. In this case, TLV74333PDBVR is not necessary to your customer because the output are 24V based on your request.

For high VDC input, slua987b could be a reference to share how to apply >700Vdc input by using UCC28730-Q1.

Please let me know if you need any assistance.

Regards,

Wesley
