Calculate PWM duty cycle and frequency.
PWM duty cycle is the percentage of time the signal stays high during one period.
The calculator applies the formula above to the values entered in the form and returns the calculated engineering result instantly.
PWM is used for LED dimming, motor control, heaters and switching regulators.
This online calculator is intended for fast engineering estimates. For production hardware, verify the result with datasheets, manufacturer recommendations and real measurements.
Calculate PWM frequency and duty cycle. This tool is designed for fast electronics engineering estimates directly in the browser.
Enter the known values, press Calculate and compare the result with your design requirements. For reliable hardware, always check component datasheets, tolerances, temperature limits and manufacturer recommendations.
Is this calculator suitable for production design?
It is useful for estimates and early design work. Final production designs should be verified with real measurements and datasheets.
Does the calculator work on mobile?
Yes. EngiCalc tools are lightweight, responsive and designed to work on desktop and mobile devices.
