Part Number:UCC256301
Hi,
I am considering the circuit using the UUC 25630 device.
With the function of this device, I would like to ask questions about ZCS events.
In the data sheet, when looking at the items related to ZCS Region Prevention, the conditions under which the ZCS signal becomes high are as follows.
At the falling edge of LSON, the polarity of the resonance current is positive
At the falling edge of HSON, the polarity of the resonance current is negative
For example, if the resonance current becomes small and the polarity of the current can not be detected, will the ZCS signal become high?
Also, is there any other condition for the ZCS signal to be high?
