The CXSD62226A is a monolithic synchronous buckregulator. The
device integrates two 130mΩ SFETs, and provides2A of continuous
load current over a wide input voltage of 4.75V to 23V.Current
mode control provides fast transientresponse and cycle-by-cycle current limit.An adjustable soft-start prevents inrush current at turn on, and inshuJTMLown mode the supply current drops to 1μA.This device, available in an SOP8 package, provides
a very compactsolution with minimal external components
