CPC H02M 3/07 (2013.01) [G06F 1/26 (2013.01)] | 16 Claims |
1. An assembly comprising:
a first three-level voltage converter having an input electrically coupled to a voltage source to receive a battery-supply voltage, the first three-level voltage converter configured to convert the battery-supply voltage to an intermediate voltage at an output of the first three-level voltage converter, the intermediate voltage lower than the battery-supply voltage;
a processor module comprising:
a processor package substrate;
a second three-level voltage converter mounted on the processor package substrate, the second three-level voltage converter having an input electrically coupled to the output of the first three-level voltage converter to receive the intermediate voltage, the second three-level voltage converter configured to convert the intermediate voltage to a processor-supply voltage at an output of the second three-level voltage converter, the processor-supply voltage lower than the intermediate voltage; and
a processor chip mounted on the processor package substrate, the processor chip having an input that is electrically coupled to the output of the second three-level voltage converter to receive the processor-supply voltage; and
a controller that adjusts the intermediate voltage depending on the battery-supply voltage and a requested voltage by the processor to maximize a voltage conversion efficiency and/or to reduce a processor-supply voltage ripple;
wherein the controller is integrated with the first three-level voltage converter, with the second three-level voltage converter and/or inside the processor chip.
