SG3525 Adjustable PWM Signal Generator Module 100Hz–100kHz

Generate adjustable PWM signals for electronics experiments, switching power supply development, inverter circuits, and other power-electronics projects with this SG3525-based PWM signal generator module.

The module uses an SG3525 PWM controller IC and provides onboard frequency and duty-cycle adjustment. Its adjustable frequency range is advertised as 100Hz to 100kHz, making it useful for experimenting with different PWM settings and testing compatible electronic circuits.

Key Features

• SG3525 PWM Controller: Based on the SG3525 pulse-width modulation controller IC.

• Adjustable Frequency: Advertised adjustment range of 100Hz–100kHz.

• Duty-Cycle Adjustment: Onboard adjustment control for changing the PWM pulse width.

• Onboard Controls: Two adjustment trimmers are specified in matching listings.

• PWM Signal Generation: Produces a PWM signal for compatible electronic circuits.

• Compact Module: Small PCB format for electronics projects and laboratory setups.

Technical Specifications

Important: Some sellers advertise this module as 5V–12V, while other matching listings specify 8V–12V. The 8V–12V range is used here conservatively. Confirm the correct input range, output amplitude, and dimensions for your stock before listing.

Applications

• Switching-mode power supply (SMPS) development and testing

• Inverter and converter control experiments

• PWM signal testing in electronics laboratories

• MOSFET and IGBT driver circuit experiments, with a suitable driver stage

• DC-DC converter development

• DIY electronics and power-electronics projects

• Educational demonstrations of pulse-width modulation

How It Works

The SG3525 controller generates pulse-width modulation signals. The frequency and duty cycle can be adjusted using the onboard controls. The generated signal can be applied to a compatible control or driver circuit after checking its voltage levels, pin configuration, and electrical requirements.

Important Usage Notes

• This is a PWM signal generator module, not a high-power motor speed controller.

• It does not directly supply motor power or provide a specified motor-current rating.

• Verify the input voltage and polarity before connecting the power supply.

• Check the actual PCB labels and output signal voltage before connecting another circuit.

• Use an appropriate MOSFET or IGBT driver when required by your application.

• Do not connect the output directly to a power load unless the circuit design and output ratings support it.

• Use an oscilloscope to check frequency, duty cycle, and signal amplitude when accurate settings are required.
