Abstract
Official abstract text for this publication.
A control circuit for controlling a switching circuit is disclosed. The control circuit has a ramp compensation circuit, a ramp regulating circuit and a comparison circuit. The ramp compensation circuit generates a ramp compensation signal with the amplitude proportional to the difference between 1 and the duty cycle of a main switch of the switching circuit. The ramp regulating circuit generates a ramp regulating signal with the amplitude proportional to the duty cycle of the main switch. The comparison circuit compares a reference signal with the sum of the ramp compensation signal, the ramp regulating signal and a feedback signal representative of an output voltage of the switching circuit, so as to provide a comparison result to control the switching circuit.
First claim
Opening claim text (preview).
I claim: 1. A control circuit for a power converter, wherein the power converter comprises a switching circuit comprising a main switch, a freewheeling element and an inductor having a first terminal and a second terminal, and wherein the power converter is configured to convert an input voltage into an output voltage, the control circuit comprises: an on-time generating circuit configured to generate an on-time control signal; a ramp compensation circuit configured to generate…
