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 power stage output node stabilizer may be used to reduce ringing of a power stage output node of a switching DC-DC power converter. The power stage output node stabilizer may be a network of resistors and switches coupling the power stage output node to a higher voltage level and a lower voltage level.

Switching regulator stability control circuit and methodology

Present invention is an apparatus and method for power conversion charge pumps that uses cross-coupling capacitors. High efficiency power converter charge pump for both divide by 3 (&#x2153;), divide by 3/2 (&#x2154;) are explicitly discussed. The power conversion charge pumps utilizing cross coupled capacitors may provide up to 40% reduction in a number of switches required for a charge pump implementation, thus reducing design area cost while also resulting in high-efficiency performance.

Apparatus and method for charge pump power conversion

A deglitch circuit, or look-back, may be used to reduce or avoid reacting to a transient overvoltage situation by a voltage regulator. The voltage regulator may delay reacting to an overvoltage situation unless the overvoltage situation persists for more than a first programmable number of cycles.
