一,产品概述(General Description)      

   The CXDR7581 IC combines a Dual synchronous Buck controller and a linear regulator controller,
providing a cost-ffective, high performance and flexible solution for multi-output applications. The Dual
synchronous controller is configured as 2-independent PWM controller. CXDR7581 provides a separate
adjustable output by driving a switch as a linear regulator. This device features an internal 200KHz
oscillator, under-voltage lockout for all input supplies, an external programmable soft start function as
well as output under-voltage detection that latches off the device when an output short is detected.
