ABSTRACT:
A circuit provides multi-module current sharing for circuit modules. The circuit includes an error amplifier having a negative and a positive input and an output. The positive input of the error amplifier is connected to a reference voltage. A buffered differential amplifier has an output connected to the negative input of the error amplifier and a positive and a negative input. A correction current is sourced to the negative input of the buffered differential amplifier. A resistor connected to the negative input of the buffered differential amplifier has a value that controls the amount of current correction applied to the negative input of the buffer differential amplifier by the current correction source.
