Abstract:
In a method arrangement, providing a zero voltage transition circuit including an input node, an output node, a switch node, an output inductor coupling the switch node and output node, an output capacitor coupling the output node and ground, a first switch coupling the input node and switch node, a second switch coupling switch node and ground, a first auxiliary switch coupling the input node to an auxiliary node, a second auxiliary switch coupling the auxiliary node to ground, and an auxiliary inductor coupling the auxiliary node to the switch node; closing the first auxiliary switch to couple the input to the auxiliary node; subsequently, when a current is below a cutoff threshold, opening the second switch; after a first delay period, opening the first auxiliary switch and closing the second auxiliary switch; and after a second delay period, closing the first switch. Apparatus and additional method arrangements are disclosed.
