Part Description

The UCC39002 device is an advanced, highperformance, and low-cost load share 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-theshelf power supplies must be paralleled. The BiCMOS UCC39002 is based on the automatic master or slave architecture of the UC3902 and UC3907 load share controllers. The device provides better than 1% current share error between modules at full load by using a very low offset post-packagetrimmed current sense amplifier and a high-gain negative feedback loop. And with the amplifier’s common-mode range of 0 V to the supply rail, the current sense resistor, RSHUNT, can be placed in either the GND return path or in the positive output rail of the power supply.
