Part Number: UCC21225A Hi team，
For the bootstrap charging path, there is a confusing question that is looking for your support.
There is a situation that HS pin is not connected to Cboot Gnd, but the connection between HS PIN and Q1 source pin/SW node…
Thank you for reply!
Q1. You say that there is no FMEA data for UCC21225A. Is that because you have already evaluated other measurement data instead of FMEA for UCC21225A? In that case, I would like to have other measurement data as a substitute…

My customer is using UCC21225A but looking for another device in parallel because of the supply constraint. The smaller package is preferred. It looks for me UCC21225A is the…
Part Number: UCC21225A Hi Team,
When my customer tried to power up with output load, it shows that the output signal of UCC21225 is not synchronous with input-signal DSP.
Please see this reference below:
I hope to hear from you soon, thank you.
Part Number: UCC21225A Dear sir,
Based on the UCC21225A datasheet, DT can be connected to VCCI that allow the output to overlap.
What about the input current of DT ( pin 6) when tying DT to VCCI?
Part Number: UCC21225A Other Parts Discussed in Thread: UCC21530 , UCC21540 Hi,
According to Datasheet of UCC21225A, the internal functional isolation between the two secondary side drivers allows working voltage up to 700-VDC.
And the distance of the…
