  • Switch-mode power supplies with improved analog-to-digital current calibration
    Patent number: 11683047
    Abstract: A switch-mode power supply includes a pair of input terminals, a pair of output terminals, and at least one switch coupled between the input terminals and the output terminals. The power supply further includes an analog-to-digital converter (ADC) for converting a sensed analog current value at the output terminals to an output digital value, an interface for receiving a user configurable current setting, and a control circuit coupled with the interface, the ADC and the at least one switch. The control circuit is configured to determine a raw digital value of the ADC that corresponds to the received current setting by processing an iterative loop, and turn on and turn off the at least one switch according to the determined raw digital value and the output digital value of the ADC, to supply an output current at the pair of output terminals that corresponds to the received current setting.
