Description

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.
FEATURES
• Fully Differential High Impedance Voltage Sensing
• Accurate Current Amplifier for Precise Current Sharing
• Opto Coupler Driving Capability
• 1.25% Trimmed Reference
• Master Status Indication
• 4.5-V to 35-V Operation
