产品概述 返回TOP
The CXSD62227A is a monolithic synchronous buck regulator. The device integrates two 130mΩ MOSFETs, and provides2.2A of continuous load current over a wide input voltage of 4.75V to 23V.
Current mode control provides fast transient response and cycle-by-cycle current limit.An adjustable
soft-start prevents inrush current at turn-on, and inshutdown mode the supply current drops to 1μA.
This device, available in an SOP8-PP package, provides a verycompact solution with minimal external components
