Abstract:
1. A power supply connected to an electrical load and configured to supply an output voltage to the electrical load, the power supply comprising: a first portion having a fast transient response topology and configured to supply a first part of an output current to the electrical load, wherein the first portion is capable of increasing the first part of the output current based on a load step event and decreasing the first part of the output current based on a load release event, and wherein a first current path carries current from the first portion to the electrical load; and a second portion having a slow transient response topology and configured to supply a second part of the output current to the electrical load such that the second part of the output current does not increase or decrease as fast as the first part of the output current, and wherein a second current path carries current from the second portion to the electrical load, wherein the first current path has a lower impedance than the second current path, and the second current path has a lower resistance than the first current path, and wherein the second current path comprises a copper wire connected to the second portion and the electrical load such that an internal inductance of the second current path is derived from the copper wire being elevated relative to a printed circuit board to which the power supply and electrical load are connected.
