SC508规格书详情
Description
The SC508/SC508A is a synchronous EcoSpeed®buck regulator which incorporates Semtech’s advanced, patented adaptive `on-time control architecture to provide excellent light-load efficiency and fast transient response. It features an integrated bootstrap switch and a fixed 5V LDO in a 3 x 3(mm) package. The device is highly efficient and uses minimal PCB area. The SC508A is available for automotive applications and is qualified to AEC-Q100.
