Reference: LT3705 Data sheet Figure 7. "36V-72V 1V/5A Isolated Forward Converter Using Optoisolator."
My question regards the 470pF capacitor across the output of the optoisolator. Is this for RF immunity and/or noise rejection? If so, can we use a different value to target specific noise frequencies?
(For example, we'd like to use a value of capacitor that presents a low impedance at the transmitting frequency of our radio product.)
Best regards,
