I have been looking into using the LTM8056 to generate 24V from a 8.5V - 34V input voltage range. I noticed in simulation that for high loads and smaller input voltages, the output power would be limited to a set value which seem independent of the adjustable output current/voltage limit. It also seems suspiciously close to the edge of the datasheet operational curves.
Although this operation is likely out of spec, could you tell me more about the mechanism which limits the power in that condition? I suspect a switch peak-current limit but I cannot find anything about that in the datasheet.
See here-under simulation results which clearly show how output voltage is held below 24V for a high load (16R).
