摘要:
A switching mode power supply with an adaptive setting of a threshold valley voltage. The switching mode power supply decreases a reference auxiliary current when a valley value of a primary switching voltage across a primary switch is smaller than a first threshold valley voltage. And in addition, the switching mode power supply can increase the reference auxiliary current when the valley value of the primary switching voltage is larger than a second threshold valley voltage.
