The SG3525ANG with Switching Controllers 8-35V PWM is an integrated circuit produced by ON Semiconductor. It is a high-performance custom linear-type controller with rectifier-type feedback control. It can be used to drive push-pull DC-DC converters, buck/boost converters, flyback converters, forward converters, and transistor inverters. It features an 8-pin PDIP package and operates from 8-35V. The controller provides a variable frequency and voltage control loop, improved overshoot and settling time, and improved line and load regulation specifications. It also includes features such as soft start, voltage lockout, ripple rejection, feedback protection, and an AUX supply on pin 4. This makes it ideal for a wide range of applications, such as automotive, telecom, and industrial power supplies.
