Multiphase DC/DC Converters Provide High Efficiency Over the Entire Load Range

摘要

Data centers presently consume an astounding 2.5 percent of the total electric power in the United States - a figure that's rising by approximately 12 percent per year and does not show any signs of slowing. As this power demand continues to increase, the need for higher efficiency power conversion is required to reduce the amount of wasted power. Smart multiphase controller technology is an excellent solution for high current applications. This architecture allows a high current regulator to achieve well over 90 percent efficiency at full load. However, most of these types of designs do not address the need for higher efficiency at light to medium loads. Wasted power at a light to medium load is just as important to save as wasted power at heavy loads.
