Abstract
In described examples, a phase interleaver obtains (i) a first signal indicating a variance between a reference voltage and a regulated output voltage and (ii) a second signal indicating a voltage across an energy storage device. A voltage regulator includes multiple phase blocks collectively configured to generate the regulated output voltage. In a repeating cycle, (i) the voltage across the energy storage device is increased while the second signal is less than the first signal and (ii) in response to a determination that the second signal is greater than the first signal, the energy storage device is substantially discharged, multiple stages of a clock divider are transitioned in the phase interleaver, and a set of control signals is output from the clock divider. The control signals have a common switching frequency and a common switching period. The control signals control the phase blocks active in generating the output voltage.
