Unlike the LM317 (linear regulator) or LM2596 (buck converter), the LM2577 lacks a native SPICE simulation model in Proteus’s standard distribution. Attempting to search for “LM2577” in the Pick Devices dialog yields no results. Without a model, you cannot simulate transient response, feedback loop stability, or output voltage regulation under load. lm2577 proteus library

Diode backwards or inductor too small. Fix: Check diode orientation (cathode to output cap). Increase inductor to 220 µH. Without a model, you cannot simulate transient response,
