This switching regulator uses the SEPIC topology to provide a regulated output voltage that can be higher than, the same as, or lower than the input voltage, making it great for applications with widely-varying power supplies and for battery-operated applications where the battery transitions from being above the output to below the output as it discharges. The small (0.4″×0.7″) module can support input voltages from 1.5 V to 12 V, has an adjustable output from 2 V to 12 V, and can supply over 300 mA in typical applications.
