This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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, tele, 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.

Key Features

  • 1 High Accuracy, Better Than 1% Current Share Error at Full Load.
  • High-Side or Low-Side (GND Reference) CurrentSense 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 MSOP Package Minimizes Spa.
