The is a legendary pulse-width modulation (PWM) controller IC. Developed in the 1970s, it remains a cornerstone for designing switching power supplies, DC-DC converters, inverters, and battery chargers. For engineers and students, simulating circuits before hardware implementation is critical. Proteus Design Suite is one of the most popular platforms for this purpose, offering powerful schematic capture and mixed-mode SPICE simulation.
