If you are designing Switched-Mode Power Supplies (SMPS), inverters, or DC-DC converters, the SG3525 is likely the heart of your project. It is a pulse-width modulator (PWM) control circuit that offers improved performance over the older SG3524.

The SG3525 is a legendary PWM controller chip. It is the gold standard for push-pull converters, DC-DC converters, and high-frequency inverters. However, despite its popularity, Proteus (the industry-standard simulation software) often ships without a native simulation model for the SG3525. The Ultimate Guide to Finding and Using the
