摘要：A switched-mode power supply with a control loop and a microprocessor has a

normal mode and a low-power mode with a burst mode. The microprocessor is

connected via an output to the control loop and uses this to control the burst mode ofthe switched-mode power supply directly. The control loop of the switched-mode powersupply monitors, in particular, a secondary output voltage, so that the output of themicroprocessor is connected to the control loop, for example via a simple resistornetwork or a transistor stage. The clock frequency and the duty cycle of the burst modeare permanently stored in the microprocessor and can be defined for the switched-modepower supply directly, for example using TTL logic.
