The LM5080 is a simple and cost effective load share controllerthat provides all functions required to balance thecurrents delivered from multiple power converters operatedin parallel. The LM5080 implements an average program(AP) method of active load share control which adjusts theoutput voltage of individual power stages either up or downto deliver nearly equal currents to a common load. Theaverage program method improves stability and reduces theoutput voltage tolerance when compared to other commonload sharing methods. The LM5080 supports two commonapplications for load share controllers: external control inwhich the load share circuit balances currents betweenseparate power modules (bricks), and internal control wherethe load share circuit is integrated into the voltage regulationloop of each power converter module or circuit.
