Abstract: Droop monitors spread across a system-on-chip (SoC) monitor for voltage droops in regulated supply voltage supplied to logic circuitry of the SoC. In the event of a voltage droop, a clock signal supplied to the logic circuitry is stretched, to temporarily increase a period of the clock signal. The droop monitors may include a sensing delay line provided voltage at the regulated supply voltage, and a reference delay line supplied with a reference voltage, with operations of the delay lines monitored to determine a voltage droop.

In some embodiments the digital circuitry determines the load current differently based on whether the DC-DC converter is operating in pulse frequency modulation mode or pulse width modulation mode. In some embodiments the DC-DC converter includes circuitry for determining if a short circuit or over current condition exists.

Abstract: A switching power regulator provides for power regulation for a load, based at least in part on comparison of an output voltage with a reference voltage. The reference voltage may be changed, and in some cases changed dynamically, while regulated power is provided to the load. The switching power regulator may include a bypass switch for coupling ends of an output inductor.
