Abstract: A circuit includes a microcontroller having a first terminal and a second terminal. The microcontroller is configured to: receive a signal associated with operation of a power converter at the first terminal; adjust a switch control signal at the second terminal responsive to the signal; measure a frequency of the switch control signal; compare the measured frequency responsive to at least one envelope of a set of envelopes to obtain monitoring results; and perform control operations responsive to the monitoring results.
