Description

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 using a very low offset post-package-trimmed current-sense amplifier and a high-gain negative feedback loop.
