Abstract
A power adapter device includes a rectifier bridge, a transformer, and a power delivery integrated circuit (PD IC). The rectifier bridge includes input terminals that receive an alternating current (AC) voltage for the power adapter device, and output terminals. The transformer includes a primary side that is coupled to one of the output terminals of the rectifier bridge, and a secondary side that includes a secondary side coil and a sub-coil. The PD IC is coupled to the sub-coil of the transformer. The PD IC determines a direct current (DC) voltage across the sub-coil of the transformer. Based on the DC voltage, the PD IC determines a voltage level of the AC voltage and stores the determined voltage level of the AC voltage.
