Abstract: Various embodiments provide a voltage regulator circuit including two or more discontinuous conduction mode (DCM) phases coupled to an output node and coupled in parallel with one another. A control circuit may detect a trigger and switch all of the two or more DCM phases to a first state (charge state) responsive to the detection. The control circuit may switch a first DCM phase, of the two or more DCM phases, to a second state (discharge state) after a first predetermined time period in the first state and may switch a second DCM phase, of the two or more DCM phases, to the second state after a second predetermined time period in the first state, wherein the second predetermined time period is different than the first predetermined time period. Other embodiments may be described and claimed.

Abstract: Embodiments herein relate to a circuit which generates a sawtooth waveform based on an adaptive feedback loop that self-corrects the ramp up rate to account for variations in a device. The sawtooth waveform is obtained by repeatedly charging and discharging a capacitor according to a clock signal. The sawtooth waveform can be sampled once per clock period at a comparator which provides a corresponding binary output to a state machine. If the binary output indicates the amplitude of the sawtooth waveform is below a desired maximum voltage, the state machine outputs a code word to a digitally-controlled variable current source to increase the output current. The sawtooth waveform can be used to provide a pulse-width modulated (PWM) waveform such as for a DC-DC converter.

Abstract: Embodiments herein relate to identifying, by phase current balancing (PCB) circuitry, an indication of whether a measured current of a pulse-width modulated (PWM) signal of a plurality of PWM signals is greater than or less than an average current of the plurality of PWM signals. Embodiments further relate to adjusting, by the PCB circuitry, a bias-value of a non-modulated edge of a duty cycle of the PWM signal. Other embodiments may be described and claimed.
