I am using a LM5085 in a design for some LED drivers.
I made my circuit but the output voltage was the same as input, however according to my calculations it should be around 4v (adjustable with a trim pot).
Circuit is posted below. Im glad I tested using a 10 volts supply otherwise the output caps would have blown!
the mosfet that I use is a STLD70N10F4 with a .0195 Ohm Rds
I tested the circuit with no load
