Hello,
I have a question about UCC28070-Q1.
If it is the case that PKLMT-terminal is OPEN, how becomes the setting of the Peak Current Limit?
1.
There is pull-down resistance of the high impedance to lead to GND inside, and PFC does not work because it is equipotential to GND.
2.
The voltage becomes unsettled, and the behaviour becomes unstable.
3.
It becomes equipotential to VREF, and the Peak Current Limit becomes large.
The above is expectation, how about?
Regards,
Daisuke
