A New Self-oscillating,Mode-switching DC-DC Converter Using Full Inductor Current Sensing Technique

摘要：

In this paper,a self-oscillating DC-DC converter with a proposed mode-switching mechanism is presented. The proposed mode-switching mechanism employs a full inductor-current sensing technique to enable the automatic switching among CCM,DCM and idle modes according to the level of the load current and an idle signal, thus maintaining the high conversion efficiency over wide load range. The maximum power efficiency can be up to 93.5% while the output current ranges between 50mA and 350mA. The dc to dc converter operates at a switching frequency from 300 to 1.7MHz. The new DC-DC converter was fabricated in TSMC 0.35-μm 2P4M CMOS process with die size was 1.96mm21.
