- Abstract
- The present disclosure a switched-mode power supply using a reconfigurable delta-signal modulator (DSM). The switched-mode power supply comprises, a current sensing unit configured to determine an operation mode on the basis of a result of sensing a current of an output terminal; a compensator configured to output a compensation signal by amplifying a difference value between an output voltage and a reference voltage; a reconfigurable DSM configured to output a digital signal by noise-shaping the compensation signal; a power switch unit switched by the digital signal to output an output voltage; and an attenuator configured to supply a feedback voltage of the output voltage attenuated by a voltage divider to the compensator.
