We are having trouble with our product malfunctioning due to noise entering pin 4 "SNSCURPFC" of the TEA1716T. Therefore, we would like to connect a capacitor to remove the noise entering pin 4 to GND. Is it possible to connect a capacitor between pin 4 "SNSCURPFC" and GND to stabilize the PFC operation of the TEA1716T? And please tell me up to what pF a capacitor can be connected.
Thanks for the reply. The problem is solved!
Yes you can!
Thank you for reply.
Noise interference on pin 4 "SNSCURPFC" caused the PFC OCP to malfunction.
Inserting a Cstart(soft) capacitor did not improve the situation, but connecting a 220pF capacitor between pin 4 and GND fixed the malfunction.
Is it permissible to connect a capacitor between pin 4 and GND?
Hi
We recommend current sense circuit below,what kind of noise did you found?
If the high frequency noise you can try to connect nf level capacitor to try test.
