A direct current (DC)/direct current (DC) voltage converter includes: a first stage operable to convert a first DC voltage rail into a second DC voltage rail different from the first DC voltage rail; and a second stage operable to convert the second DC voltage rail into a third DC voltage rail lower than the second DC voltage rail, and to deliver current to a load in the third DC voltage rail. The amount of the current delivered to the load corresponds to an operating set point of the second stage. The second stage is operable to change the operating set point of the second stage in response to a command received from the load, so as to reduce the amount of the current delivered to the load. The first stage is operable to change an operating set point of the first stage in response to a command issued by the load, so as to reduce the amount of current delivered to the second stage. |
