UCC39002是一种先进的，高性能的负载共享控制器，提供所有必要的功能，以并联多个独立的电源或直流 - 直流模块。DescriptionThe UCC39002 is an advanced, high-performance load-share controller that provides all the necessary functions to parallel multiple independent power supplies or dc-to-dc modules. This load-share circuit is based upon the automatic master/slave architecture utilized in the UC3902 and UC3907 load-share controllers providing better than 1% current-share error between the modules at full load. Features

       

• High accuracy, better than 1% current share error at full load       
  
• High-side current sensing       
  
• Ultra-low offset current sense amplifier       
  
• Single wire load-share bus       
  
• Intel® SSI load-share spcification compliant       
  
• Disconnect from load-share bus at stand-by       
  
• Load-share bus protection against shorts to GND or to the supply rail       
  
• 8-pin MSOP package option minimizes board space       
  
• External or internal bias selection       
  
• External shutdown switch for each module
