STMicroelectronics L6615 High/Low Side Load Share Controller Datasheet

L6615 is a controller IC specifically designed to achieve load sharing of paralleled and independent power supply modules in distributed power systems, by adding only few external components. Current sharing is achieved through a single wire connection (share bus) common to all of the paralleled modules.
