I am getting a behaviour of LTC3112 that I do not understand. I am using it very close to the schematic recommendations in the datasheet. It works perfectly fine until my power supply (TOE 7610-60) goes into current limiting (at 2.5 Amps). The current limit is only reached due to switching peaks in the current, but not actually used by the circuitry. Then the LT3112 seems to get stuck and constantly draws 2.5 Amps (and gets really hot).
I have done a simulation with LT Spice, that does not show this behaviour. Note the voltage source V2 (going from 0.5 V to 0V in steps) and the voltage source V (with current limiting for 2.5 Amps).
In short: the power supply reaches its current limit and even if I decrease the output current of LTC3112, the power supply keeps outputting 2.5 Amps.
