UCC39002数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The UCC39002 device is an advanced, high-performance, 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-the-shelf 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-package-trimmed 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.
