How do I calculate the needed resistance for the VIN_SENSE (Pin 16) for the LT3798? This is for a PFC, variable input frequency (>400Hz) application. Is this pin looking for a voltage input or a current input? There are different values used on different examples. There is a reference to a LT3799 IC that uses a voltage divider.
Also, are there any thoughts on the input inductor, L2, to the rectifier on page 17 of the LT3798 data sheet?
Thanks,
Doug
