Power improvement for minimum switching frequency operation

A method for operating a data storage device, the method comprising:

• determining a minimum switching frequency;
• determining, based at least in part on determining the minimum switching frequency, a start time of a switching cycle for a first regulator of the data storage device, wherein the first regulator is associated with a first voltage rail;
• and
• at or near the start time of the switching cycle, coupling the first regulator to a second regulator of the data storage device to initiate the switching cycle,
• wherein the second regulator is associated with a second voltage rail, and
• wherein at least one of a switching frequency of the second regulator is greater than a switching frequency of the first regulator and the first voltage rail is associated with a higher voltage than the second voltage rail.

One or more processing devices, comprising:

• means for determining a minimum switching frequency;
• and
• means for identifying, based at least in part on the determined minimum switching frequency, a start time of a switching cycle for a first regulator of a data storage device, wherein the first regulator is associated with a first voltage rail;
• and
• means for coupling the first regulator to a second regulator of the data storage device to initiate the switching cycle at or near the start time, wherein the second regulator is associated with a second voltage rail, and wherein at least one of a switching frequency of the second regulator is greater than a switching frequency of the first regulator and the first voltage rail is associated with a higher voltage than the second voltage rail.
