Tool/software:
Hi, I was working on a flyback power supply design and was making use of the WEBENCH POWER DESIGNER tool using the UCC287506DBV.
Looking at the datasheet I think the circuit is mostly correct, but this capacitor Cfb3 seems strange to me.
I don't see the point of connecting this capacitor to the optocoupler emitter.
I think you would expect to connect the emitter to ground directly and in which case connect the capacitor to the collector.
I don't know if it's a bug or the circuit may work like this, but it's not a configuration I've looked at much and the datasheet doesn't seem to do this.
