The SG3524DR with Switching Controllers Regulating Pulse Width Modulator manufactured by Texas Instruments is a voltage mode pulse width modulation (PWM) control circuit designed for switching, linear and switching regulators. It includes an oscillator, two error amplifiers, a voltage reference, a dead-time control, and an output switching stage. Its features include a wide operating range, excellent transient response, programmable oscillator and dead-time control, and reverse polarity protection. It is designed as a constant frequency current-mode PWM controller to regulate the output voltage of an AC-DC power supply with a wide input voltage range and is commonly used in motor drives, switching AC/DC converters, and other control and power applications.
