TOREX的XC9221系列是多功能降壓DC/DC控制器IC。給該芯片外部配備一種開關器件，一種功率電感，一種二級管和兩個電容就能獲得一種高效率,相對穩定的，輸出電流高至3A的開關電源。能使用低ESR電容例如陶瓷電容用作其輸出電容。
XC9221系列控制器有個0.9V(±1.5%)基準電壓，采用外置采樣電阻就可以隨意設定輸出電壓。工作頻率為300kHz,500kHz和1MHz，
XC9221系列控制器能使用中小型外部器件。針對軟啟動時長，XC9221A和C系列是內部設置為4ms，XC9221B和D系列能夠在外部設定。XC9221系列控制器具備內嵌的UVLO（欠壓鎖閉）功能性，當輸入電壓降至2.3V或更低情況下，外部的P端面開關器件將會被強制性關閉。
