The SC9301MLTRT is a stand-alone synchronous EcoSpeed® buck regulator with adaptive on-time control architecture. It features integrated power MOSFETs, a bootstrap switch, and a fi xed 5V LDO in a 5x5mm package. The device is highly effi cient and uses minimal PCB area. The SC9301MLTRT supports using standard capacitor types such as electrolytic or specialty polymer, in addition to ceramic, at switching frequencies up to 1MHz.
