MOS Reference: Step-up DC-DC boost converter module with adjustable output voltage. Switching regulator steps lower input voltage up to a higher regulated output for applications requiring elevated voltage rails. Adjustable output via potentiometer accommodates a wide range of target voltages. Ideal for boosting single lithium cell voltage to 5V/9V/12V, driving LED strips from low-voltage sources, and creating higher voltage rails in battery-powered projects.
