Abstract
A control circuit for a power converter comprising switching transistors and an output inductor is disclosed. One terminal of the output inductor serves as an output node, and another terminal of the output inductor serves as a switching node. The control circuit is configured to generate a control signal for controlling switching transistors in the power converter. The control circuit includes: a RC oscillator network connected to two terminals of the output inductor, the RC oscillator network configured to generate an oscillation signal containing a feedback ramp slope compensation component in response to a change in a voltage across the terminals of the output inductor; a comparator; an on-time generation circuit; and a control signal generation circuit to generate the control signal for controlling the switching transistors in the power converter.
