Abstract: The invention relates to a switching voltage regulator incorporating a driver circuit of a MOS power switch. Advantageously, the MOS switch is formed of a plurality (n) of power transistors (M1, M2, ..., Mn) connected in parallel to each other. In particular, the first (M1) of said plurality of transistors (M1, M2, ..., Mn) has larger sizes (W1) than the other transistors, or better still, the sizes (Wi) of the individual power transistors (M1, M2, ..., Mn) scale down (W1 • W2 ≥ W3 ... ≥ Wn).
In this way, the equivalent dimensional parameter (W) of the power switch is greatly reduced by that the first and largest translator (M1) is readily turned. This is carried out without affecting the delivered current, which continues to be supplied by the remaining transistors (M2, ..., Mn).
Compared to the prior art solutions, this arrangement functions to modify the power switch own tansconductance, which decreases as the transistors are turned off onward from the first (M1).
