FEATURES

DESCRIPTION

High Accuracy, Better Than 1% CurrentShare

Error at Full Load

The UCC39002 is an advanced, high performance and

low cost loadshare controller that provides all

necessary functions to parallel multiple independent

power supplies or dc-to-dc modules. Targeted for high

reliability applications in server, workstation, telecom

and other distributed power systems, the controller is

suitable for N+1 redundant systems or high current

applications where off-the-shelf power supplies need to

be paralleled.

The BiCMOS UCC39002 is based on the automatic

master/slave architecture of the UC3902 and UC3907

load share controllers. It provides better than 1%

current share error between modules at full load by
