Everything works. Weak signal output requires a preamplifier.

UC3902D 描述

***as Instruments: Load Share Controller 8-SOIC 0 to 70

***ical: Controller -0.3V to 20V 8-Pin SOIC Tube

***ser: Power Supply Support LOAD SHARE CONTROLLER

***as Instr.: The UC3902 load share controller is an 8-pin device that balances the current drawn from independent, paralleled power supplies. Load sharing is accomplished by adjusting each supplies output current to a level proportional to the voltage on a share bus.

***AS INSTRUM: The master power supply, which is automatically designated as the supply that regulates to the highest voltage, drives the share bus with a voltage proportional to its output current. The UC3902 trims the output voltage of the other paralleled supplies so that they each support their share of the load current. Typically, each supply is designed for the same current level although that is not necessary for use with the UC3902. By appropriately scaling the current sense resistor, supplies with different output current capability can be paralleled with each supply providing the same percentage of their output current capability for a particular load.

***AS INSTRUMEN: A differential line is used for the share bus to maximize noise immunity and accommodate different voltage drops in each power converters ground return line. Trimming of each converters output voltage is accomplished by injecting a small current into the output voltage sense line, which requires a small resistance (typically 20 Ω to 100 Ω) to be inserted.
