Definition of duty cycle PCMag

WebHere we consider a step-down switching regulator in nonintermittent operation mode; that is, in continuous conduction mode. The duty cycle is independent of the switching frequency. The period T typically lies between 20 µs (50 kHz) and 330 ns (3 MHz). If the values for input voltage and output voltage are the same, a duty cycle of 1 is needed. WebMeaning of duty cycle.
