Abstract
A data storage device or disk drive may include a plurality of regulators, a first voltage rail associated with a first regulator of the plurality of regulators, a second voltage rail associated with a second regulator of the plurality of regulators, wherein a switching frequency of the second regulator is greater than a switching frequency of the first regulator, the first voltage rail is associated with a higher voltage than the second voltage rail, or a combination thereof. The data storage device may include one or more processing devices configured to: determine a minimum switching frequency, identify a start time of a switching cycle for the first regulator, based at least in part on determining the minimum switching frequency; and, at or near the start time of the new switching cycle, couple the first regulator to the second regulator to initiate the switching cycle.
