Abstract :
A new family of switching regulator ICs, the LM2577 family, and its SPICE-based macro-model are described in detail. The IC offers an easy-to-use solution for low to medium-power DC-to-DC converter applications that use a single open collector switch. Its current mode design and extensive protection features simplify the design procedure and minimization external component count. The full feature macro-model of this IC aids the switching regulator designer in optimizing and verifying his/her design quickly and cost effectively. The macro-model not only provides the standard features (DC, AC, and transient analysis), but also has built-in intelligence that can detect design-related problems and alert the user when they occur.<>
