The UCC29002 device family comprises advanced, high-performance, low-cost load-share controllers that provide 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 must be paralleled.

The BiCMOS UCC29002 is based on the automatic leader/follower architecture of predecessor UC3902 and UC3907 load-share controllers. The device is capable of 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. With an amplifier common-mode range of 0V to the VDD 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.
