Other Parts Discussed in Thread: , , UC2854, UC2854B, UC2854A, UC3854A,
Hi team,
Customer has a question regarding the UCC2818 (and its equivalents like UCC2818-EP and UCC2818A-Q1):
What is the voltage at the IAC input?
This pin needs to be connected to the input voltage of the converter through a resistor, in order to get an IAC current proportional to the input voltage.
On other controller like the UC2854 and UC2854A / UC2854B, the value of this voltage is specified.
In particular, it has been the subject of improvements, as highlighted in the Application Report SLUA177A:
thanks in advance for your help on this topic
Regards,
Pol
