Abstract:
A system and method for providing interleaving point-of-load (POL) regulators such that each regulator's switching cycle is phase displaced with respect to those of other POL regulators in the array is disclosed. As a result, the aggregate input and/or output reflected ripple and noise of the input, output, or both is reduced. Each regulator in the array is associated with an unique address. A serial data-line writes the phase spacing programmed to each addressable POL regulator in the array. The present invention permits phase displacement of POL regulators without limitation to the input and output voltages of each of the regulators in the array. The array of POL regulators may also operate in a phase displaced mode with only a single control line. The need for separate controllers and multiple control lines is thereby eliminated.
