UCC29002DGK概述

    # Texas Instruments UCC39002: Advanced 8-Pin Load-Share Controller
    Product Introduction
    The UCC39002 is a highly advanced, high-performance, and cost-effective load-share controller from Texas Instruments (TI). This device is designed to manage the parallel operation of multiple independent power supplies or DC-to-DC modules, making it ideal for high-reliability applications in industries such as servers, workstations, and telecommunications. The UCC39002 ensures precise load sharing between modules, maintaining better than 1% current sharing accuracy at full load.
    Its unique features include high-side or low-side current sensing capabilities, ultra-low offset current sense amplifiers, and a flexible load share bus for seamless integration. The controller operates in either high-side or low-side modes, allowing users to place the current sense resistor in either the ground return path or the positive output rail of the power supply, depending on the application requirements.
