LM5080

Modular Current Sharing Controller

General Description

The LM5080 is a simple and cost effective load share con-

troller 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. The LM5080 supports two common

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.
