Hello,
We are considering using UCC28600 for a flyback converter design. The input voltage range takes on a wide range from 15VDC - 400VDC. The output is +/-5V, 0.5A.
My question: is UCC28600 suitable for operation with this wide range of input voltages? If no, can anyone suggest an alternate part for this requirement?
Thanks in advance!
Pradeep.

Thanks Vincenzo.

I would not recommend the UCC28600 for such a wide input voltage range. At low line, the controller would need to switch at a frequency that is below its minimum frequency clamp and no one would be happy with the result of such an attempt.

Thanks a lot Lisa, for your inputs!
Do you have any suggestions about an alternate part that would be suitable for this?
Regards,
well... I can't think of any off hand that would support such a wide input range.
