Pololu 3.3V, 2.5A Step-Up/Step-Down Voltage Regulator S13V25F3 hub-labor Robust enclosure: M12 IP68 cableThe S13V25Fx family of efficient switching regulators (also called switched mode power supplies (SMPS) or DC to DC converters) use a buck boost topology to convert both higher and lower input voltages to a regulated output voltage. They take input voltages from 2. 8 V to 22 V and increase or decrease them as necessary, offering a typical efficiency of over 85% and typical continuous output currents between 1 A and 3 A. The flexibility in input voltage
