1. A switching power supply comprising:
a voltage ramp generator comprising at least one output capacitor,
wherein the voltage ramp generator is configured such that the output capacitor has a first value during a first operating cycle of a first operating mode and a second value during subsequent operating cycles of the first operating mode, the second value being different from the first value, the first operating cycle and the subsequent operating cycles being part of a same continuous conduction mode, the change in capacitance from the first value to the second value being triggered by a change in operating cycle from the first operating cycle to the subsequent operating cycles.
