SG3524 – Regulating Pulse Width Modulator (PWM) Controller IC (DIP-16)

Description

The SG3524 is a versatile, monolithic Pulse Width Modulator (PWM) control circuit specifically designed for switching regulator systems. It contains all the necessary components for building a power supply control circuit, including a voltage reference, an error amplifier, a current-limiting circuit, an adjustable oscillator, and a pulse-steering flip-flop.

This IC is widely used in high-efficiency DC-to-DC converters, switching power supplies, and motor speed control circuits. Its design allows for both single-ended and push-pull output configurations. By providing a stable reference voltage and precise PWM generation, the SG3524 enables the construction of reliable power conversion systems with minimal external components. Its DIP-16 package makes it highly convenient for breadboarding and through-hole PCB assembly in industrial and hobbyist projects.
