一,产品概述(General Description)      

   The CXDR7580 IC combines a Dual synchronous Buck controller, providing a cost-effective,
high performance and flexible solution. The CXDR7580 can configured as 2-independent or
as 2-phase controller. The 2-phase con-figuration is ideal for high current applications. The
     CXDR7580 features 180 out of phase operation which re-duces the required input/output
capacitance and results to few number of capacitor quantity. Other key features offered by this
device include two independent program-mable soft starts, programmable switching frequency up
to 500KHz per phase, under voltage lockout function.The current limit is provided by sensing the lower
MOSFET's on-resistance for optimum cost and perfor-mance
