SG3525 PWM Controller Module – Adjustable Frequency & Pulse Width Driver for Inverters

Overview 

The SG3525 Adjustable PWM Controller Board is designed for electronics enthusiasts and engineers who need a stable, reliable signal for switching power devices. Whether you are building a push-pull inverter, a battery charger, or a custom DC motor speed controller, this board provides the necessary “pulse” to drive your MOSFETs or IGBTs with precision. It features an adjustable potentiometer to fine-tune your frequency and duty cycle on the fly.

Key Features 

• Precise Control: Onboard potentiometer allows for easy adjustment of output frequency and duty cycle.

• Versatile Output: Designed to drive power switches directly or through a gate driver stage.

• Stable Performance: Built with high-quality components to ensure minimal jitter in the PWM signal.

• Easy Integration: Standard headers make it breadboard-friendly or easy to mount inside a custom chassis.

• Robust Design: Short-circuit protection and soft-start capabilities inherent to the SG3525 architecture.
