Abstract
A mode-transition architecture for USB Type-C controllers is described herein. In an example embodiment, an integrated circuit (IC) controller includes controller includes a controller coupled to a slope compensation circuit, the controller to cause the slope compensation circuit to apply a first slope compensation to the input current in a first mode in which the buck-boost converter is operating in a discontinuous conduction mode (DCM). The controller detects a transition of the buck-boost converter from a first mode having a first duty cycle to a second mode and causes the slope compensation circuit to apply a second slope compensation to the input current. The second slope compensation starts at a maximum offset of the first slope compensation.
