Hello Jim,
I looked through the UCC28064 product folder and could not find an excel design tool I am guessing this is either the UCC28060/1 or 3 design tool. These tools did calculate the RT resistor based on the maximum on time at the minimum line…
Part Number: UCC28061 Other Parts Discussed in Thread: UCC28060 , I've noticed the UCC28061 datasheet makes mention of the parameters KTH, KTHS, KTL, KTLS and uses some in equations on pages 16 and 17. These parameters are not applicable to the UCC280961…
We have UCC28050 EVM of 100W and not have a design for 350W that about 400W. For such a power range, you may think about UCC28060 family. But if you do need single phase transition mode, you would have to design or request PDS to design for you.
For…
Other Parts Discussed in Thread: UCC28063A , UCC28180 , UCC28060 , UCC28061 , UCC28063 , UCC28220 Hi
My customer consider using UCC28180, UCC28060, UCC28061, UCC28063A.
THey think they input DC110V into them to the circuit designed to input AC100…
Hi Lawrence,
Attached is a document outlining the main electrical differences between the UCC28060 and the UCC28061 2112.60vs61 (UG)2.pdf
and another document that highlights the main differences between the UCC28061 and the UCC28063
Differences…
Hello Robert,
In a sysntem where a PFC boost is used generaly there is a stepdown converter to step the PFC outrput voltage to a usable voltage. Genererally there is an aux power sypply in the systeme to power all the logic and power supply controllers…
Hi Adil,
Assuming you want a single stage flyback topology using 2-interleaved phases with isolation, then the UCC28060 is a good choice for your ~ 2+ kW output. Look at the our reference design PMP10116 200W Natural Interleaving Transition-Mode PFC…
Hi Stephan
I've added this issue in our 'submit documentation feedback' system for the UCC28063A and for the related UCC28063, UCC28061 and UCC28060 devices. The correction should be included in the next update cycle for these parts but I don't know…
Other Parts Discussed in Thread: UCC28070 , UCC28060 Hi,
I have reviewed the UCC28070 Implement Bridgeless Power Factor Correction (PFC) Pre-Regulator Design document.
It's a 200W CCM application, how if I want a semi-bridge less PFC which operate…
Hello David
Firstly, my apologies for the delay in getting back to you - I was travelling on business.
I think your logic is correct and your offset adjustment modification is acting as I would expect. Unfortunately there is no method available…
