DESCRIPTION
This controller IC is specifically designed to
achieve load sharing of paralleled and indepen-
dent 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 paral-
leled modules.
