An apparatus and method for current sharing among multiple power supplies is disclosed. The output current of each power supply is compared in an amplifier which produces an output signal. This signal controls a transistor used to enable or disable current flow on a SENSE line in a particular power supply. By controlling the SENSE line, the output current of each power supply is adjusted to roughly equal levels. The combined current is thereby the combination of approximately equal shared outputs of each individual power supply. The current share of each individual power supply is offset by a predetermined level to prevent a race condition in the initial power-up phase.
