一,产品概述(General Description) 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 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持</span>！</span> |
