摘要
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 configured to sense current traveling through an inductance, a dual threshold generator configured to generate a first and a different second threshold, and a comparator system configured to compare current sensed by the current sensing system with the first threshold when the DC-to-DC converter is operating in the continuous current mode and with the second threshold when the DC-to-DC converter is operating in the discontinuous current mode.
