Hello Shotaro-san,
You are correct to question my reply. I based my answer on my previous experience with designs that operate down to 85Vac input. I di not "do the math" for your high-voltage only case.
In fact, using Rvs1 = 85kR (from the Excel…
Hello Harish,
thank you for reviewing my calculation sheet.
Unfortunately, I don't have the right tools to unsolder the controller without risk of breaking it, so I tried to replace (for the second time) the UCC28780 with another one, of course taken…
Part Number: UCC28780 Tool/software: Hi.
I downloaded the simplis file to simulate and play a little bit with the model. But when I click on run,it doesn't run the simulation. I tried with other circuit that I am working for my master and it is working…
Part Number: UCC28782EVM-030 Other Parts Discussed in Thread: UCC28780 , LMG2610 , UCC28782 , Tool/software: Hello team,
My customer is looking for tool to evaluate UCC28780+ LMG2610.
What is difference between UCC28780 and UCC28782?
Can we switch UCC28782…
Part Number: UCC28780 Tool/software: Hello. I have designed an isolated DCDC converter using this IC and am testing it right now. I'm asking this question because I ran into a problem during testing that I can no longer resolve. In the startup sequence…
Part Number: UCC28782 Other Parts Discussed in Thread: TPA3251 , UCC28780 , , UCC2893 , TL431 I'd like to design about Audio AMP.
We will adopt TPA3251 as classD Amp.
On the other hand , I will use UCC28780 as Power supply of TPA3251.
So would you please…
Part Number: UCC28780 Other Parts Discussed in Thread: UCC27712 I am interested in knowing if this controller can be used in AC output applications at 60 Hz. In other words, is it possible to modulate the reference voltage at 60 Hz to yield an AC waveform…

Part Number: UCC28780 Hello,
I'm designing an AC/DC power supply 115Vac@400Hz to 32Vdc and in primary side I’m facing startup issues with UCC28780RTE.
in the power on phase I get in SWS pin around 3.01V and for VDD, 1.83V, and it doesn’t allow…
