Abstract

A voltage converter includes a high side power transistor coupled to an input voltage node and a low side power transistor coupled to the high side power transistor at a switch node. The switch node is configured to be coupled to an inductor. A slope detector circuit is configured to receive a signal indicative of a current through the inductor. The inductor current is a triangular waveform comprising a ramp-up phase and a ramp-down phase. The slope detector circuit also is configured to generate an output signal encoding when the inductor current is ramping up and when the inductor current is ramping down.
