摘要: Maintaining high efficiency at light-load conditions is extremely important in most modern power management applications, where the predominantly digital loads spend majority of their time idle mode. The objective this paper to review circuit and system-level techniques used leverage existing process technologies order achieve over a wide load range. main focus on low-power dc-dc converters operating above several MHz. Existing fixed variable frequency schemes are contrasted work, namely pulse-frequency modulation with adaptive on-time, burst-mode control, gate swing, segmented power-stage, resonant drivers capacitive charge recovery.
