Some embodiments provide a multi-phase DC/DC switching converter in which each of the phases are controlled using a common comparator for comparing an output voltage of the switching converter and a reference voltage, with in some embodiments each of the phases including a bypass switch for coupling ends of an output inductor of the switching converter. Some embodiments provide a multi-phase DC/DC switching converter in which some of the phases are operated with clock signals having frequencies different than clock signals used for operating others of the phases. Some embodiments provide a multi-phase DC/DC switching converter in which some of the phases include inductors having inductances different than inductances for inductors of others of the phases.

Configurable-speed multi-phase DC/DC switching converter with hysteresis-less phase shedding and inductor bypass

A scalable switching regulator architecture may include an integrated inductor. The integrated inductor may include vias or pillars in a multi-layer substrate, with selected vias coupled at one end by a redistribution layer of the multi-layer substrate and, variously, coupled at another end by a metal layer of a silicon integrated circuit chip or by a further redistribution layer of the multi-layer substrate. The vias may be coupled to the silicon integrated circuit chip by micro-balls, with the vias and micro-balls arranged in arrays.

Switched power stage with integrated passive components

Circuitry may monitor a processor supply voltage and pull power from the processor supply on a temporary basis when the supply voltage rises above predetermined levels. In some embodiments this may be done without explicit knowledge of a commanded supply voltage level for the processor.

Method and apparatus for improving integrity of processor voltage supply with overshoot mitigation and support for DVFS

Dedicated circuitry may monitor a processor supply voltage and provide additional power on a temporary nano-second scale basis to the processor when the supply voltage drops below predetermined levels. This may be done without explicit knowledge of a commanded supply voltage level for the processor.

Method and apparatus for improving integrity of processor voltage supply with support for DVFS

A fault detection circuit may be used to determine if voltage supplied by a voltage regulator as power to sequential logic circuitry falls below a minimum voltage expected to be required by the sequential logic circuitry for proper operation. Information regarding voltage levels supplied to the sequential logic circuitry prior to such an occurrence may be written to a memory, for example to allow for further analysis.

Realtime critical timing path potential fault event detection and prevention for embedded cores

Design of a power delivery network (PDN) is integrated with a digital logic design flow.

Integrated system of PDN implementation and digital co-synthesis

A scalable switching regulator architecture has an integrated inductor. In some embodiments an area and current drive capability of switches of the switching regulator is matched with an inductor built within an area above the switches. In some embodiments the combined switches and inductor are constructed as a unit cell and can be combined to form larger elements as required for higher current drive capability and multiphase operation.

A regulated DC-DC switching converter includes a bypass mode in which ends of an output inductor are coupled together. Circuitry determines output capacitor current and load current components of output inductor current during operation of the switching converter, for use in controlling switching operations.

DC-DC converter with digital current sensing

A voltage regulator and/or associated circuitry provides an indication of average current consumed or drawn by a load, level and magnitude of transient events, and regulation efficiency. A dynamic voltage and frequency scaling governor makes use of the indication of average current consumed or drawn by the load, level and magnitude of transient events, and regulation efficiency to help optimize operation of the load, with respect to power and/or performance.

Load aware voltage regulator and dynamic voltage and frequency scaling

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.

Integrated thermal and power control

Automatic transient control circuitry may be used to alleviate issues relating to large changes in power demands by a load in an integrated circuit. The transient control circuitry may inject current to or retract current from a load, for example charging or discharging a bypass capacitor associated with the load, when circuitry of the load is commanded to an operational state from a standby state or vice-versa, respectively.

Transient power control

The disclosure relates to a method of generating an output voltage, comprising: generating a regulated output voltage from a high voltage source; providing an inductor having a first terminal and a second terminal linked to a low voltage source by a capacitor, the second inductor terminal supplying the output voltage to a load; connecting the first inductor terminal exclusively either to the high voltage source or to the low voltage source or to the second inductor terminal, as a function of command signals to reduce a difference between the output voltage and a reference voltage lower than a high voltage supplied by the high voltage source; and generating a square binary control signal having a duty cycle substantially adjusted to the ratio of the output voltage to the high voltage; the first inductor terminal being connected to the high voltage source or to the low voltage source as a function of a binary state of the control signal.
