Part Number: UCC28750 Hello,
We're working with the UCC287505 in 2 separate designs. The first is AC to DC solution and we need an opto coupler.
However the other design is low voltage DC to DC flyback and we would like to remove the opto.
Is it possible…
Part Number: UCC28750 Other Parts Discussed in Thread: ATL431 , PMP31288 , , TL431 Hello,
We're working on a UCC287505 flyback design.
One version of the solution is AC input and we need to isolate the secondary.
however a different version is using…
At this time, I am not sure which one is best for my application. But, I think that UCC28742 is good enough, even though
UCC28750 has more advanced features.
Thanks,

Hi Daniel,
We don't have any reference designs for PD at 20W. The lowest power AC/DC reference design with PD is 45W: https://www.ti.com/tool/PMP40183
For lowest cost solution, I would recommend our new UCC28750 device at this power level. https://www…
Hi Stefan,
Thank you for reaching out.
Unfortunately most offline flybacks (especially PSRs) like UCC2871x/ UCC28700/ UCC28730 etc. have constant current control. So there are no other options in this family of devices.
On the SSR options, there is this…

Hi Dean,
There are several options to create a bias supply. The cheapest of which would be our new UCC28750 . If you want to achieve the absolute lowest standby power, the UCC28730 could be an option.
I hope this helps you to get started.
Hi Thomas,
If price is your #1 criterion, the UCC28750 is your best option. For solution size, the UCC28911 might be an option.
Both support frequency dithering and are widely available.
I hope this answers your question.
