产品概述 返回TOP
The CXSD62228A CXSD62228B is a monolithic synchronous buck regulator. The device integrates two 130mΩ MOSFETs, and provides3.2A 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, andin shutdown mode the supply current drops to 1μA.This device, available in an SOP8-PP package, provides a verycompact solution with minimal external components.
