Claim:
1. A current balance circuit for a power management device having a first current channel and a second current channel, comprising: a first terminal coupled to an input terminal of the first current channel; a second terminal coupled to an input terminal of the second current channel; a third terminal coupled to an output terminal of the first current channel; and a fourth terminal coupled to an output terminal of the second current channel; a first current sense circuit having an input terminal coupled to the input terminal of the first current channel to detect a current flowing through the first current channel, and an output terminal configured to provide a first current sense signal indicative of the current flowing through the first current channel; wherein the current balance circuit draws current from the second current channel to the first current channel based on the first current sense signal.
