The FIVR must provide high conversion efficiency across a wide operating range of output voltages and load currents, including light to medium loads, to maximize the overall energy efficiency of the SoC across different power states. Phase shedding and switch scaling have been used for high-frequency FIVR designs with pulse-width modulation (PWM) control in continuous conduction mode (CCM) to maintain high efficiency for large load
