Abstract
A switching power supply comprising: a first power supply stage configured to receive an AC input voltage and to generate a DC output voltage, wherein the DC output voltage of the first power supply stage is set to a first target level during a first load condition and, otherwise, the output voltage is set to a second target level, the second target level being higher than the first target level. A level of power provided to a second power supply stage by the first power supply stage may be monitored to determine whether the switching power supply is operating in accordance with the first load condition or the second load condition. A level of the regulated DC output voltage May be adjusted according to a level of power drawn by the switching power converter in order to maintain a switching frequency of the resonant switching converter at or near its resonant frequency.
