SG3525 (3525) Pulse Width Modulation Controller IC DIP 16 Package

SG3525 (3525) Pulse Width Modulation Controller IC DIP 16 Package 

The SG3525 is a versatile Pulse Width Modulation (PWM) controller IC designed for use in switch-mode power supplies (SMPS), DC-DC converters, inverters, and motor control applications. It provides all the necessary control and drive functions required for efficient and reliable power conversion.

The IC features a precision oscillator, error amplifier, soft-start control, dead-time control, and dual alternating outputs, making it ideal for push-pull, half-bridge, and full-bridge converter topologies. Packaged in a DIP-16 through-hole package, the SG3525 is easy to use for prototyping, educational projects, and industrial power supply designs.
