The output voltage of the DC to DC converter is less than or greater than the input voltage. The output voltage of the magnitude depends on the duty cycle. WebFigure 7 shows the two inputs for the power stage: the input voltage and the duty cycle. The duty cycle is the control input. This input is a logic signal, which controls the switching action of the power stage and hence the output voltage. Most power stages have a nonlinear voltage conversion ratio versus duty cycle. notifier nfw 50 datasheet
