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…
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 …
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:
L1 - components…
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.
BR,
frank
