The switch stores input energy in L1. During the off interval the inductor discharges through the diode into the negative output. The output magnitude may be above or below the input, but its polarity is reversed. The guest starts near the calculated operating point.
Vout=−1−DDVin
Ideal continuous-conduction, open-loop power stage with fixed PWM duty. No feedback controller, switch loss, capacitor ESR or inductor resistance is included in the equations. The guest uses near-ideal switches and diodes. Inputs outside the continuous-conduction or small-ripple range are rejected.
