The old model ignored the inductor's parasitic elements. The new library includes proper CCM (Continuous Conduction Mode) and DCM (Discontinuous Conduction Mode) simulation. You will now see the sawtooth ripple on the output capacitor. Adjust your LC filter values in simulation and watch the ripple change in real-time—exactly like on a scope.
A quick restart of Proteus, and there it was—a sleek, multi-pin version of the LM2596 that actually supported the wide 3V to 40V input range his hardware required. proteus lm2596 library updated
PCB designers will appreciate the new compatible footprints: The old model ignored the inductor's parasitic elements
