<p>A valley current mode DC-to-DC converter may include an electronic control system configured to cause the DC-to-DC converter to operate under a continuous current mode and a discontinuous current mode. The electronic control system may include a current sensing system (509,511) configured to sense current traveling through an inductance (501), a dual threshold generator (523) configured to generate a first (V1) and a different second threshold (V2), and a comparator system (517,518) configured to compare current sensed by the current sensing system (511,509) with the first threshold (V1) when the DC-to-DC converter is operating in the continuous current mode and with the second threshold (V2) when the DC-to-DC converter is operating in the discontinuous current mode.</p> |
