LM5080 Modular Current Sharing Controller January 2006 LM5080 Modular Current Sharing Controller General Description The LM5080 is a simple and cost effective load share controller that provides all functions required to balance the currents delivered from multiple power converters operated in parallel. The LM5080 implements an average program (AP) method of active load share control which adjusts the output voltage of individual power stages either up or down to deliver nearly equal currents to a common load. The average program method improves stability and reduces the output voltage tolerance when compared to other common load sharing methods.
