1. A dc-dc voltage converter comprising:

  • a slice comprising;

    a step-down converter comprising at least one monolithically formed regulator coupled to a capacitor and an inductor, wherein the at least one monolithically formed regulator comprises a switching controller, a switch, and a rectifier in a buck-type configuration, and wherein the switching controller operates at a load-dependent switching frequency in excess of approximately one megahertz; and

    an oscillator-less-control circuit that monitors an output voltage of the step-down converter and when the converter falls below a given threshold voltage the oscillator-less-control circuit produces at least one set of dynamic switching pulses usable for triggering the switch and the rectifier.
