摘要：In an arrangement comprising a switched-mode power supply with a controlloop and a microprocessor, the switched-mode power supply has a normal mode and alow-power mode with a burst mode. The microprocessor is connected via an output tothe control loop and uses this to control the burst mode of the switched-mode powersupply directly. The control loop of the switched-mode power supply monitors, inparticular, a secondary output voltage, so that the output of the microprocessor isconnected to the control loop, for example via a simple resistor network or a transistorstage. The clock frequency and the duty cycle of the burst mode are permanently storedin the microprocessor and can be defined for the switched-mode power supply directly,for example using TTL logic.
