Abstract
The present invention relates to a digitally controlled switched-mode power supply, wherein a switched-mode power supply is provided with a control circuit, which comprises a signal amplifier unit able to receive digital signals or analog signals and a switching controller able to receive the signals. The switching controller uses the signals to produce a clock signal, after which the clock signal is output, whereupon the signal amplifier unit feeds a signal back to control the switching controller. The signal amplifier unit is provided with at least one amplifier element, and when the amplifier element receives a digital signal or analog signal, then the signal is transmitted to the switching controller. Accordingly, the control circuit achieves the effectiveness to not only receive and transmit digital signals, but also receive and transmit analog signals, and is thus provided with the advantage of enormous flexibility.
