Abstract
A switching power converter includes a power circuit including at least two power switching devices and a control circuit coupled to the power circuit for controlling the power switching devices. The control circuit is configured to sense an output voltage of the power circuit, generate at least two ramp signals based on complementary clock signals, and generate a control signal for controlling one of the power switching devices based on one of the ramp signals and the output voltage of the power circuit, and another control signal for controlling another one of the power switching devices based on another one of the ramp signals and the output voltage of the power circuit. In some examples, the control circuit may include comparators for generating the control signals. Other example power converters and control circuits are also disclosed.
