Abstract
A power system is disclosed including a plurality of power circuits, each power circuit providing an independent power output and including a high-side driver coupled to a high-side switch and a low-side drive coupled to a low-side switch, and control circuitry coupled to each of the power circuits. The control circuitry is operable to detect a present state of each high-side and low-side switch, and prevent two or more of the high-side switches from substantially concurrently switching from a first state to a second state, or two or more of the high-side switches and one or more of the low-side switches from substantially concurrently switching from a third state to a fourth state, or two or more of the low-side switches from substantially concurrently switching from the third state to the fourth state.
