Extend Low-Voltage Digipot Resolution to Control an Adjustable Regulator (.PDF Download)

    Jan. 21, 2016

    A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output. Typically, the output voltage is determined by the ratio of two resistors. Replacing one or more of these resistors with a digital potentiometer (“digipot”) opens the door to digital control of the output voltage. Taking that route is attractive given the common availability of inexpensive microcontrollers and the software infrastructure that supports devices such as the Arduino and Raspberry Pi...
