LM5080 Datasheet | National Semiconductor

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 mon load. The average program method improves stability and reduces the output voltage tolerance when pared to other mon load sharing methods. The LM5080 supports two mon applications for load share controllers: external control in which the load share circuit balances currents between separate power modules (bricks), and internal control where the load share circuit is integrated into the voltage regulation loop of each power converter module or circuit.
