    • Described is an apparatus that comprises: a programmable delay line (PDL) to receive a pulse-width modulation (PWM) signal as input and to generate a first output; a selection unit operable to provide PWM signal or its inverted version as a second output; and a sequential unit coupled to the PDL, the sequential unit to sample the second output with the first output, the sequential unit to generate a pulse-frequency modulation (PFM) output. Described is also a voltage regulator which comprises: mutually coupled on-die inductors for coupling to a load; a bridge, coupled to the mutually coupled on-die inductors, including a low-side switch and a high-side switch; a PWM controller for controlling the low-side and high-side switches during a first load current; and a PFM controller for controlling the low-side and high-side switches during a second load current, the second load current being smaller than the first load current, the PFM controller comprising: a comparator for comparing output voltage of the load with a reference voltage; and a first PDL coupled to the comparator for determining turn-on duration of the high-side switch.
