Abstract
In an embodiment, a method for operating a USB-PD power adaptor comprises operating a first buck circuit comprising a first switch connected between a supply voltage terminal and a first USB port based on a first target voltage and a supply voltage at the supply voltage terminal, responsive to the first target voltage being less than the supply voltage plus an offset voltage, operating the first buck circuit in a variable-buck-input mode to control the first switch according to a first duty cycle based on the first target voltage and the supply voltage to generate the first target voltage at the first USB port, and responsive to the first target voltage being equal to the supply voltage plus the offset voltage, operating the first buck circuit in a buck-bypass mode to maintain an on state of the first switch to generate the first target voltage at the first USB port.
