UC3907N概述

    UC3907 Load Share Controller Technical Manual
    1. Product Introduction
    The UC3907 is a member of the UCx907 family of load share controllers designed for applications requiring parallel operation of multiple independent power modules. These controllers ensure that each module contributes its proportional share to the total load current, thereby achieving balanced load distribution and optimal performance. Key functionalities include a fully differential high-impedance voltage sensing mechanism, precise current amplification for current sharing, and opto coupler driving capability. Additionally, the UC3907 supports a 1.25% trimmed reference voltage, enabling accurate adjustments for precise operations.
    The UC3907 operates within a wide voltage range of 4.5V to 35V, making it suitable for diverse applications including industrial control systems, telecommunication equipment, and data center infrastructure. The device is particularly beneficial in scenarios where redundant power supply configurations are employed to enhance reliability and fault tolerance.
    2. Technical Parameters
    Below are the key technical specifications extracted from the product manual:
    | Parameter | Value |

    | Operating Voltage Range | 4.5V to 35V |
    | Reference Voltage Accuracy | ±1.25% |
    | Current Sense Gain | 20 (internal fixed) |
    | Input Offset Voltage | ≤60mV |
