Part Number: UCC28019A Hi
The customer's waveform of MOSFET is as attached.
There is a section in which the gate is off and the MOSFET operates.
Certain samples perform this operation, and the EMI's conduction is also not good.
Can I know what…
Part Number: UCC28019A Other Parts Discussed in Thread: UCC28180 , UCC28070 Hi team,
My customer would like to use this as a PFC chip at the front end of a design. They want to know if there is any limitation of using the chip from the power perspective…
Hi Livia,
I will see if I can locate and share the unencrypted PSPICE models. I will contact you via internal email to continue this discussion.

Part Number: UCC28019A Hi,
I am designing the power stage of a system based on the UCC28019A.
I went over the datasheet and followed the calculator side by side with the datasheet.
Everything was one to one except for Cvins that for some reason didn't…
David,
Customer removes the LMG3410EVM-031. They found the UCC28019A evm already has issue. Maybe the UCC28019A is damaged.
I will apply the UCC28019A sample to replace the one on EVM.
Thanks.

Part Number: UCC28019A For the brownout protection, it is recommended in the datasheet to use R VINS1 less than 10MOhm. As per my design, the input voltage minimum (V AC(on) ) is150V, so R VINS1 comes around 14MOhm. I also considered 150 times input bias current…

Hi,
In fact, I have used the UCC28019A for an AC/DC board that should operate from 100V 50/60 Hz to 265V 50/60 Hz, everything is working fine for me. In the case of 265V, I reached a power of 1200 W for an output voltage of 400V…
