The invention relates to switch mode power supply modules and items of equipment powered by these modules. The power supply module comprises means for cyclically interrupting the switching operation, during a so-called switching operation interruption phase, if the load current of the module is less than a current threshold value and sustaining the switching operation, during a so-called switching operation phase, if the load current is greater than the load current threshold value and means for ending the switching operation interruption phase if the power supply voltage of the item of equipment is greater than a voltage threshold value. The item of equipment powered by the module comprises a capacitive element able to store energy from the module during the switching operation phase and means for releasing the energy stored between the output terminals of the power supply module when it receives an activation signal. |
