A multi-output DC/DC converter (1;10;30;40;50;60), comprising inductive electrical energy storage means (L), switching means (S0-S7) and control means (6;9;31;41;51;61). The control means (6;9;31;41;51;61) are arranged for selectively operating the switching means (S0-S7) for transferring an amount of electrical energy from the energy storage means (L) to an output (A;B;C;D) of the DC/DC converter (1;10;30;40;50;60) providing an output voltage in accordance with a switching sequence based on comparing, by the control means (6;9;31;41;51;61) of the output voltage of each output (A;B;C;D) with an associated reference voltage. The control means (6;9;31;41;51;61) are arranged for operatively controlling the switching means (S0-S7) for each output (A;B;C;D) in accordance with an output individual switching cycle, wherein the switching sequence is comprised of the output individual switching cycles for transferring electrical energy to the outputs (A;B;C;D) of the multi-output DC/DC converter (1;10;30;40;50;60) in a predetermined order of priority.
A multi-output DC/DC converter, comprising inductive electrical energy storage means, switching means and control means, wherein said control means are arranged for selectively operating said switching means for transferring an amount of electrical energy from said energy storage means to an output of said DC/DC converter providing an output voltage in accordance with a switching sequence based on comparing, by said control means of the output voltage of each output with an associated reference voltage, characterised in that said control means are arranged for operatively controlling said switching means for each output in accordance with an output individual switching cycle, wherein said switching sequence is comprised of said output individual switching cycles for transferring electrical energy to said outputs of said multi-output DC/DC converter in a predetermined order of priority, and wherein electrical energy is transferred to an output having a higher priority during a next switching cycle.
