<p>The converter (1) has a classic variable-voltage regulator circuit (3) operating at a frequency, and a specific variable-voltage regulator circuit (4) operating at another frequency lower than former frequency. A switching unit (5) is connected to each regulator circuit for selecting one of the regulator circuits to trigger the regulator circuit based on an external electrical parameter supplied to the direct current-direct current converter. An independent claim is also included for a low-power transmitter-receiver comprising a direct current-direct current converter.</p> |
