Control Concepts to Improve Light Load Efficiency - Optimal Number of Phases, Baby-Buck Channel, and Adaptive Bus Voltage Positioning
Light load efficiency is as important as heavy load efficiency to switching power supplies. Optimizing light-load efficiency is often conflicting with optimizing heavy-load efficiency. To increase light-load efficiency without sacrificing heavy-load efficiency, the Optimal-Number-of-Phase (ONP) control concept is proposed to optimize multi-phase ...
