Victor,
The UCC28500 latest datasheet in rev C, Nov 2001, so it looks like you have the latest.
For combo controllers, the most recently-released part available is UCC29950 - this is a combo of CCM PFC + LLC isolation stage, targetted at high-power…

Hello Anthony
We don't have a detailed procedure for this but the .pptx file attached shows the general approach that would work. In summary - you would…
Hi Rohith,
It is possible to use the UCC29950 without the UCC27511 for a 300W application. It is also possible to replace the UCC27714 high voltage bridge driver with a gate drive transformer directly driven by the UCC29950 controller.

Hi Wang, Many thanks for the reply, hope you doing well. 1. In the second question, I'm asking while I was connecting the battery with the TIDA-00704, it starts feeding the battery with 31v, 10.9A via J1 terminal, but now its output is 0v only always…
Hello Michael
As Peter said, it depends on the specific controller. Some controllers need to see a zero crossing at the AC input in order to detect a 'loss of input power' condition. If they don't see the zero crossing, they time out and eventually…
Hello Mahesh,
To the best of my knowledge there is no LLC controller available with Pulse by Pulse current limit.
The current waveshape in an LLC converter is sinusoidal and therefore it is not possible just to place a comparator and terminate the…
Hello Kuramochi-san
You are correct that there is a similar issue at DMAX when the UCC29950 is operating at current limit. In your case the system seems to be operating at Dmax but not at the current limit point and I think the problem is due to noise…

Hi Cristi Vasilache,
Please take a look at this application note:

It is intended for a different controller (UCC29950), but outlines a different approach to LLC converter analysis/design. It should be applicable…
