    Abstract: A power controller having good transient performance and including a voltage regulator and one or more (K) transient recovery circuits is described. The voltage regulator receives a supply voltage and generates a regulator output signal used to generate K output voltages for K loads. Each transient recovery circuit detects for transients in a respective output voltage and corrects the detected transients. In one design, the transient recovery circuit compares the output voltage against a low threshold voltage, detects a low transient when the output voltage is below the low threshold voltage, and couples the output voltage to a high voltage to correct the low transient. Alternatively or additionally, the transient recovery circuit compares the output voltage against a high threshold voltage, detects a high transient when the output voltage is above the high threshold voltage, and couples the output voltage to a low voltage to correct the high transient.

    Abstract: The present disclosure describes aspects of power regulation with charge pumps. In some aspects, an integrated circuit (IC) includes multiple processor cores and a power input connected to an internal power rail of the IC. The IC may also comprise embedded charge pumps coupled between the internal power rail of the IC and respective input power rails of the multiple processor cores. Capacitors of the embedded charge pumps may be implemented with on-die capacitors suitable for integration with a die of the circuit to facilitate the embedding of the charge pumps. Alternately or additionally, separate input power rails of the processor cores and the embedded charge pumps may enable more-efficient power regulation or power management on a per-processor core basis, such as when a processor core is throttled or idled to reduce power consumption.

    Abstract: Exemplary embodiments are related to a buck regulator. A buck regulator may include an inductor selectively coupled to an output and a power supply. The regulator may also include a controller configured to detect an over-current event if an amount of current flowing from the power supply to the inductor is equal to or greater than a current threshold and detect a low-voltage event if a voltage at the output is less than or equal to a reference voltage. Further, in response to the over-current event and the low-voltage event, the controller may be configured to prevent current from flowing from the power supply to the inductor until substantially all energy stored by the inductor has been dissipated.
