High Accuracy, Better Than 1% CurrentShare  
Error at Full Load  
The UCC39002 is an advanced, high performance and  
low cost loadshare controller that provides all  
necessary functions to parallel multiple independent  
power supplies or dc-to-dc modules. Targeted for high  
reliability applications in server, workstation, telecom  
and other distributed power systems, the controller is  
suitable for N+1 redundant systems or high current  
applications where off-the-shelf power supplies need to  
be paralleled.  
High-Side or Low-Side (GND Reference)  
Current-Sense Capability  
Ultra-Low Offset Current Sense Amplifier  
Single Wire Load Share Bus  
Full Scale Adjustability  
Intel SSI LoadShare Specification Compliant  
Disconnect from Load Share Bus at Stand-By  
The BiCMOS UCC39002 is based on the automatic  
master/slave architecture of the UC3902 and UC3907  
load share controllers. It provides better than 1%  
current share error between modules at full load by  
Load Share Bus Protection Against Shorts to  
GND or to the Supply Rail
