摘要： In a switching mode power supply, an input received from the secondary side of the transformer 7 and indicative of the power being drawn by the loads is used to control the timing of bursts. The input is compared with two threshold different threshold values V2, V3, and switching is enabled if the input rises above a first higher threshold value V2, and disabled if it falls below a second lower threshold value V3. A memory device FF1 controls a current limitation circuit which limits currents in the primary of the transformer when the switching mode power supply is operating in the burst mode.

摘要： A control circuit for a power supply having a controllable switch for switching a current through a first transformer winding and a voltage providing circuit for providing an output voltage based on a voltage generated in a second transformer winding has a comparing unit for generating a comparison signal. The control circuit has a threshold signal modulation circuit adapted to modulate the threshold signal that the comparison signal is activated as soon as the input signal crosses a first threshold value, if the current flowing through the switch exhibits a first current slope rate, and that the comparison signal is activated as soon as the input signal crosses a second threshold value, if the current flowing through the switch exhibits a second current slope rate smaller than the first rate. For a given voltage, the first threshold is smaller than the second threshold.
