Hi, I use the PG-pin of the LT3045 to drive an optocoupler (Anode: Vin, Cathode: PG-pin via resistor). What is the maximum current for the PG-pin? Vin is 5V. Vout is 1.2V
I simulate that question in LTspice and in the model of the LT3045 the PG-pin acts like a switch to GND with a 400R series resistor. But in reality The PG-pin acts different.
