一, 产品概述(General Description) 
The CXSD62232 is a monolithic synchronous buck regulator. The device integrates two 90mΩ MOSFETs, and provides2.2A of continuous loadcurrent over a wide input voltage of 4.75V
to 37V.Current mode control provides fast transient response and cycle-by-cycle current limit.An adjustable soft-start prevents inrush current at turn-on, and inshuJTMTown mode
the supply current drops to 1μA.This device, available in an SOP8-PP package, provides a verycompact solution with minimal external components
