Abstract

A system has an input and an output. The system includes a voltage converter, including first transistor coupled to the input and to a first switching node, second transistor coupled to the first switching node and to ground, third transistor coupled to a second switching node and to the output, fourth transistor coupled to the second switching node and to ground, and an inductor having a first terminal coupled to the first switching node and a second terminal coupled to the second switching node. The system also includes a controller coupled to the voltage converter, the controller including a state machine and a plurality of drivers to control the transistors of the voltage converter. The state machine is adaptable to cause the second and fourth transistors to conduct and the first and third transistors not to conduct, in response to current through the inductor being less than a current threshold.
