UC3907DW Description

Short technical summary and product information.

The UC3907DW from Texas Instruments is a specialized integrated circuit designed to enable multiple independent power modules to be paralleled, ensuring each module contributes its proportionate share to the total load current. This is achieved by controlling each module's power stage with a command generated from a voltage-feedback amplifier.

 

The device monitors the current from each module and designates one as the master, adjusting other modules to match its output current within 2.5%. It features a low-impedance, noise-insensitive current share bus signal.

 

Key electrical characteristics include a wide operating voltage range of 4.5V to 35V and a precise 1.25% trimmed reference. The UC3907DW also offers fully differential high impedance voltage sensing and an accurate current amplifier for precise current sharing. It has opto-coupler driving capability and master status indication.

 

Packaged in a 16-SOIC (0.295", 7.50mm Width) surface mount package, the UC3907DW operates within a temperature range of 0°C to 70°C. Its primary application is as a load share controller, making it suitable for systems requiring robust and balanced power distribution.
