The UC3907 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.
