Patent
Multi-phase switching regulator
TL;DR: In this article, the authors present a means for direct insertion of total inductor output current information into a regulator's voltage-mode control loop, to provide active voltage positioning (AVP) for the output voltage.
Patent
Multiple-phase DC-DC converter topology
TL;DR: In this article, an additional phase is added to the N phase currents to improve the converter's response to changes in load, which can reduce the magnitude of output voltage overshoot that occurs on load release.
Patent
Switching power supply control
TL;DR: In this paper, a switching power supply controller includes a comparator to compare a feedback signal to a first limit and a second limit, one of which includes a ramp, which is used to generate limit signals in response to power supply signals, control signals, and/or output signals.
Patent
Efficient voltage converter methods and structures
Doug Osterhout,Tod F. Schiff +1 more
TL;DR: In this paper, a group of inductors and at least two sets of buck and sync transistors are arranged with the group so that conducted currents through each of the sets are directed through a respective one of the inductors, and further directed to magnetically couple induced currents in the respective inductor of at least an associated set.
Patent
Switching power supply control with phase shift
TL;DR: In this article, the phase shift logic is used to reset an oscillator that controls the PWM signal, and the output of the phase-shift logic may be used for resetting the oscillator.
