Don R Dignam

Title: Don R Dignam: Innovator in Electronic Systems

Introduction

Don R Dignam is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of electronic systems, particularly in the area of point of load (POL) regulation. With a total of 2 patents to his name, Dignam's work has had a considerable impact on the efficiency and performance of electronic devices.

Latest Patents

Dignam's latest patents focus on the synchronization and phase offset of point of load regulators. His innovative electronic system includes multiple POL regulators that supply a regulated voltage to components within the system. A phase spreading scheme is implemented to ensure that the POL regulators operate under various phases, which helps to reduce voltage noise, high input capacitance, and high radiated emissions. One of the phase spreading schemes involves a single POL regulator controlling the phase spreading, allowing other POL regulators to operate under different phases. Another scheme features an upstream POL regulator determining a phase offset that is passed to a downstream POL regulator, enabling it to operate under a different phase relative to the upstream regulator.
