DESCRIPTION

· The UCC29002 device family comprises advanced, high-performance, low-cost load-share controllers for paralleling multiple independent power supplies or DC-to-DC modules.

· Targeted for high-reliability applications in server, workstation, telecom, and other distributed power systems.

· Suitable for N+1 redundant systems or high-current applications where off-the-shelf power supplies must be paralleled.

· Based on the automatic leader/follower architecture of predecessor UC3902 and UC3907 load-share controllers.

FEATURES

· High accuracy with <1% current-share error at full load.

· High-side or low-side (GND-referenced) current-sense capability.

· Ultra-low offset current-sense amplifier.

· Single-wire load-share bus.

· Full scale adjustability.

· Intel® SSI load-share specification compliant.

· Disconnect from load-share bus at stand-by.

· Load-share bus protection against shorts to GND or to the supply rail.

· 8-pin VSSOP package minimizes space.

· Lead-free assembly.

APPLICATIONS

· Modules with remote-sense capability.

· In conjunction with the internal feedback E/A of OEM power supply units.
