S13VxFx Step-Up/Step-Down Voltage Regulators

The S13VxFx family of efficient switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) use a buck-boost topology to take an input voltage from 2.8 V to 22 V and increase it or decrease it as necessary to produce the desired regulated output voltage. They offer typical efficiencies of over 85% and typical maximum continuous output currents between 1 A and 3 A . The flexibility in input voltage offered by this family of regulators is especially well-suited for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.

Step-Up/Step-Down Voltage Regulator S13V25Fx, bottom view with dimensions.

This family includes several extra-compact (0.35″ × 0.475″) versions that output a fixed 5 V with different maximum output current capabilities along with a set of larger (0.9″ × 0.9″) versions that can do even more current with output voltages from 3.3 V through 15 V. These larger units have reverse-voltage protection up to 20 V while the smaller units do not have reverse-voltage protection.
