SG3525 Integrated Circuit – DIP Package

The SG3525 is a pulse width modulation (PWM) controller IC designed for power supply and DC-DC converter applications. It provides precise control of the output voltage and current with adjustable duty cycle and frequency, making it ideal for switch-mode power supplies and motor control.

Key Features

• Adjustable PWM frequency up to 400 kHz
• Dead-time control for preventing shoot-through in power transistors
• Under-voltage lockout to ensure stable operation
• Soft-start feature to limit inrush current
• Output control for driving power MOSFETs or BJTs
• Dual output PWM signals for push-pull or half-bridge applications
• Available in DIP package for easy prototyping and replacement

Applications

• Switch mode power supplies (SMPS)
• DC-DC converters
• Motor speed controllers
• Battery chargers
• Inverters

Package Contents
