Управление питанием - Специального назначения UCC29002D

Контроллер распределения нагрузки , 4.375В до 14.25В вход, SOIC-8

The UCC29002D is an advanced 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 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 0V 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.

• High accuracy, better than 1% current share error at full load
• High-side or low-side (GND reference) 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
