SC9301中文资料SC9301,10A EcoSpeed® Integrated FET Regulator with 5V LDO and Hiccup Restart数据手册Semtech规格书

描述 Description

The SC9301 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 SC9301 supports using standard capacitor types such as electrolytic or specialty polymer, in addition to ceramic, at switching frequencies up to 1MHz.
