ABSTRACT:
A DC-to-DC converter includes an inductor and a diode that are connected in series between a positive supply terminal and a positive output terminal, and a storage capacitor connected between the positive output terminal and a negative terminal. The DC-to-DC converter further includes a first switch including a lateral MOS transistor connected between the anode of the diode and the negative terminal, a second switch including a vertical MOS transistor connected in parallel to the first switch, a first active load circuit connected between the positive and negative supply terminals and designed to control the first switch, a second active load circuit connected between the positive output terminal and the negative terminal and designed to control the second switch, and an oscillator providing a periodic signal for controlling the active loads.
