Abstract
In one general aspect, a system can include an electromagnetic interference (EMI) filter, an alternating current (AC) rectifier bridge operatively coupled to the electromagnetic filter, the AC rectifier bridge providing a first voltage, a first power stage including a step-down transformer, the first power stage configured to receive the first voltage and output a second voltage, a second power stage configured to receive the second voltage and configured to convert the second voltage to a third voltage, and a power delivery adapter controller configured to receive at least one input indicative of a requested voltage value and configured to provide at least one output for use by the second power stage, the second power stage configured to determine a value for the third voltage based on the at least one output.
