Other Parts Discussed in Thread: UCC3817A , UCC3817 , UCC3818 Posted on Behalf of a Field Engineer,
I see that you have both a UCC3817 and UCC3817A device which should I use?
There are a few more recommendations that I can make.
1. Make sure high frequency bypass capacitors are as close to the pins they are trying to filter and ground as possible.
2. Also make sure your signal ground to the IC is quite. No power stage switching…
Part Number: UCC28070 Other Parts Discussed in Thread: UCC28180 , UCC28064A , UCC28019A , UCC2817 , UCC3817 , UCD3138A Hi,
Does the UCC28070 supports for both AC as well as DC input?
I tested it in hardware by giving DC input, I have observed that the output…
Hi Shinichi-San,
Thank you for the query on UCC28070.
The UCC28070 is designed for single phase applications only. There is no separate Kvff table for 3 phase case.
So for single phase case since your input voltage range is from 254Vpk to 311Vpk, so Imo…
Hi,
Thank you for the query on UCC28070.
It should be possible to UCC28070 in three phase configuration as shown in the figure below. But we do not have any solution demonstarting this configuration.

It can also be used in a delta…
Hi,
Thank you for the query on UC3854.
I am not sure on cost but UC1854 is capable of operating upto 125C as per the specifications.
You can probably look at UCC28180 and UCC28019. Both are CCM PFCs and should be capable of being used for high power levels…
Part Number: UCC3818A Other Parts Discussed in Thread: UCC3817 Dear Team,
Here is Kevin from Delta Taiwan team.
Customer is testing UCC3818A, it seems during startup the DRVOUT pin will have some driving signal.
Do we have more information explain this…
Hello Vicky,
The UCC28180 , UCC28019A UCC3817 ,UC2854B can all be used in this application.
The UCC28070 or UCC28070A are the only part that cannot be used.
Regards

Other Parts Discussed in Thread: UCC3818 , UCC3817 Hello,
Can you suggest a PWM controller for a non-isolated boost converter which should work on single phase rectified ac, as well as three-phase rectified ac.
