We are busy with a design using a MIC9130 based on the following development kit: http://ww1.microchip.com/downloads/en/DeviceDoc/MIC9130-Power-Over-Ethernet-IEEE802.3at-PoE-Plus-PD-...

From what I understand from the datasheets the CYPD3174 can control the output voltage by driving the opto LED. I could not find much information about calculating the R and C values going to FB pins and the feedback resistor values for the CATH/COMP pin. Can someone please send me more information about these?
