Abstract
A DC voltage converter of the quasi-resonant Buck type includes an input port having a first terminal designed to receive a voltage level to be converted, an output port having a first terminal designed to supply a converted voltage level, a first switch connected in series to the first terminal of the input port and a regulation circuit configured for: generating a ripple voltage, rising or falling depending on a closed or open state of the first switch; generating a setpoint signal proportional to a difference between an average level of converted voltage and a reference voltage; performing a first comparison between the setpoint signal and the converted voltage level to which the ripple voltage has been added; and depending on the result of the first comparison, generating or not an activation signal on its output controlling the closing of the first switch for a predefined period.
