description In an information handling system, a multi-phase electrical converter includes an electrical input, an electrical output, a plurality of converter phases coupled with the electrical input and the electrical output, and a controller to ramp operation of one or more of the converter phases as a load demand adjusts. In an embodiment the converter may be a multi-phase buck converter having a high side switch, a low side switch, and an inductor. In an embodiment, the controller may ramp operation of the converter phases by adjusting a duty cycle of the high side switch. In an embodiment, the controller may adjust a phase angle of one or more of the converter phases, wherein the adjustment may be relative to the ramping operation of the one or more of the converter phases.
