Hello,
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…
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…
Part Number: UCC28019A
Hi,
I am designing a board using the UCC28019A,
I saw an example of the layout on the EVM and some points on the datasheet.
The EVM uses a 2 layers PCB while my PCB is 6 layered.
The stack up of the layers is usually…
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…
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…
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…
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…
Part Number: UCC28019A Other Parts Discussed in Thread: UCC28019 Hi Team,
May I ask if we have UCC28019A PSPICE model? I notice on TI.com we only have UCC28019 PSPICE. My customer is using UCC28019A as PFC controller and would like us to provide PSPICE…
