Part Number: UCC28019A
My customer has the following question.
It is PFC Controller P/N: UCC28019ADR. If we add one relay as below picture to control PFC , Is it has any consequence? or it is ok? Please advise us.
Thanks and best regards,M.HATTORI
You will not be able to do this.If you wish to turn on/off the VCC bias supply to the UCC28019A you should place a semiconductor switch between the node labelled "VDD12VB" and the + side of the C125 capacitor.A small signal MOSFET or a bipolar transistor is suitable for this but a relay is not.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
