DESCRIPTION  
The UCx907 family of load share controller ICs provides all the necessary features to allow  
multiple-independent-power modules to be paralleled such that each module supplies only its proportionate share  
to total-load current.  
This sharing is accomplished by controlling each module’s power stage with a command generated from a  
voltage-feedback amplifier whose reference can be independently adjusted in response to a common-share-bus  
voltage. By monitoring the current from each module, the current share bus circuitry determines which paralleled  
module would normally have the highest output current and, with the designation of this unit as the master, adjusts  
all the other modules to increase their output current to within 2.5% of that of the master.  
The current share bus signal interconnecting all the paralleled modules is a low-impedance, noise-insensitive line  
which will not interfere with allowing each module to act independently should the bus become open or shorted to  
ground. The UC3907 controller will reside on the output side of each power module and its overall function is to supply  
a voltage feedback loop. The specific architecture of the power stage is unimportant. Either switching or linear designs  
may be utilized and the control signal may be either directly coupled or isolated though the use of an optocoupler or  
other isolated medium.  
Other features of the UC3907 include 1.25% accurate reference: a low-loss, fixed-gain current-sense amplifier, a fully  
differential, high-impedance voltage sensing capability, and a status indicator to designate which module is  
performing as master.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
