Hi! just noticed that in this SMPS design(using ICE2QR2280G as PWM controller) the feedback controller which is the optocoupler is connected in between the diode rectifier and the inductor filter, why it connected in there? is this common to all SMPS circuit? Can it be connected across that output since it is monitoring the load power for regulation and overvoltage sensing.. thanks..View attachment Infineon-ICE2QR2280G-1-Demoboard-AN-v01_01-EN.pdfView attachment Infineon-ICE2QR2280G-1-Demoboard-AN-v01_01-EN.pdf
