Digital power circuit diagram

Digital power circuit diagram (1)

Below is a digital power supply circuit based on LM338, the diagram below allows to obtain the necessary output voltage level using a digital signal supplied to the base of the transistor . The size of each resistor in the transistor's collector circuit is chosen based on the desired output voltage.

Digital power circuit diagram (2)

Below is a digital adjustable power supply circuit based on LM338 , the design given below incorporates discrete transistors which can be individually digitally triggered to obtain the relevant voltage levels at the output. The collector resistance values ​​are selected in increasing order so that a correspondingly varying voltage can be selected and made available via an external trigger.
