Abstract
A switching power supply architecture comprises a power factor correction circuit adjusting an output for a post-stage circuit based on an output of the overall architecture; a resonant conversion circuit comparing its own output voltage with a comparison voltage value; and a wide input range step-down circuit disposed in sequence. When the comparison voltage value is greater than its own output voltage, an operating frequency of the resonant conversion circuit is the same as a resonant frequency. When the comparison voltage value is less than its own output voltage, an operating frequency of the resonant conversion circuit is greater than the resonant frequency, and the resonant conversion circuit is driven in a burst mode. Heat generated by operation of the switching power supply architecture is not concentrated in the power factor correction circuit and the resonant conversion circuit, but is dispersed and generated in associated circuits.
