Switch controlled power supply circuit diagram
Source: InternetPublisher:spectrum Keywords: Switch control power circuit diagram output voltage BSP Updated: 2020/08/30
The picture shows the power supply circuit controlled by the switch . Use switches S1 and S2 to set the power supply output voltage . It can be set in 256 steps and the step voltage is 70mV. In this way, the maximum output voltage of the circuit is about 18V. Controlling switch S1 can increase the output voltage from 0V to 18V, and S2 can reduce the output from 18V to 0V. Due to the addition of a reset circuit, the output voltage can be adjusted from OV
