Thanks for the update. I highly recommend getting a current probe as magnetic components are hard to debug without measuring current. If you do not have a current probe available, you can try measuring the voltage across your current resistor…

I have simulated TINA average model of UCC28019A for 2.5kW classic PFC and have questions related to the MOSFET circuit.
In the UCC28019A EVM design ( here ), resistor R1, R5 and…
Part Number: UCC28019A Hi
Current oscillation occurs at AC100V / above 550W.
My customer wants to design a 700W system.
My customer said it was not coil saturation. Which part value should be adjusted?
And the ripple factor in the input capacitor is usually…
Part Number: UCC28019A Other Parts Discussed in Thread: UCC28019 Hello,
In the thread I referenced, the gate waveforms from the IC, on time is coming out to be maxed out.
As per the explanation mentioned in the thread:
"If you notice, your COMP voltage…
Part Number: UCC28019A Other Parts Discussed in Thread: UCC28180 Hi team, Does UCC28019A depend on the frequency of the input voltage for operation? For example, is there a possible problem if the input voltage frequency is very low or very high? Sincerely…
It has been more than 3 weeks since our last correspondence. I will assume this issue has been resolved. If you still require support, please open a new ticket. If this have been resolved, feel free to close out with the RESOLVED button.
Part Number: UCC28019A Hi Team,
My customer using this part in their 675W project then they find very high peak current when doing AC drop out in 10ms at 279Vac.
But it is working well at 90vac drop out.
I give them some suggest to adjust his Vcmop …
