Duty-commanded buck — control-to-output

A buck whose duty is a command, so its frequency response to that command can be measured.

Open and simulate Check the LTspice comparison status

Duty-commanded buck — control-to-output circuit and simulated waveform in PWMSim — This is the editable circuit and completed result in PWMSim. You can review the values, model type, and recommended waveform before opening it.

Try this first

In Analysis, choose Control-to-output response and sweep 100 Hz to 5 kHz.

The app opens this template, adds the recommended probe, and runs it once. Change the suggested value and run it again to compare the results.

Limits

This example works in the browser, but it is not a promoted LTspice comparison, hardware design, or certification. Check the app for model limits. It does not cover packaging, layout, thermal behavior, or operating conditions that are not listed.
