Abstract:
DC/DC converter (1; 20), comprising inductive electrical energy storage means (L), switching means (S1-S4) and control means (6; 15) wherein said control means (6; 15) are arranged for selectively operating said switching means (S1-S4) for transferring an amount of electrical energy from said energy storage means (L) to an output of said DC/DC converter (1; 20), for providing a desired output voltage (Vout), characterized by digital control means (6; 15) which are configured for operatively controlling said switching means (S1-S4) for transferring electrical energy in accordance with a switching sequence comprising one of:a ramp-up switching cycle for substantially charging the energy storage means (L); and a ramp-down switching cycle for substantially dicharging the energy storage means (L).
