<p>The voltage converter circuit (20) has first and second input terminals (21a, 21b), and first and second output nodes (22a, 22b), and comprises: a first power switch (60) connected between the first input terminal (21a) and the first output terminal (22a); a second power switch (70) connected between the first output terminal (22a) and the second input terminal (21b); a first delay circuit (64) having first and second terminals connected between the first input terminal (21a) and a control terminal (61) of the first power switch (60); and a second delay circuit (74) having first and second terminals connected between the first output terminal (22a) and a control terminal (70) of the second power switch (70). Each delay circuit (64, 74) detects a variation in the voltage supplied on the respective first terminal and detects an operating condition of the respective power switch (60, 70) on the second terminal, and supplies to the control terminal (61, 71) of the respective power switch (60, 70) a switching on delay signal (E). <IMAGE> <IMAGE> <IMAGE></p> |
