This powerful synchronous switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2.8 V and 22 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The board measures 9mm × 12mm, has a typical efficiency of 85% to 95%, and can supply a typical continuous output currents between 1 A and 2 A depending on the input voltage.

The S13VxF5 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 5 V output. 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 offered by this family of regulators is especially well-suited for battery-powered applications in which the battery voltage begins above 5 V and drops below as the battery discharges. 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.

The different members of this family offer different continuous output currents:
  • S13V10F5: 1 A continuous output current
  • S13V15F5: 1.5 A continuous output current
  • S13V20F5: 2 A continuous output current
  • S13V30F5: 3 A continuous output current

The regulators have under-voltage lockout, output over-voltage protection, and over-current protection. A thermal shutdown feature also helps prevent damage from overheating and a soft-start feature limits the inrush current and gradually ramps the output voltage on startup. The larger 3 A S13V30F5 has reverse-voltage protection up to 20 V, but the S13V10F5, S13V15F5, and S13V20F5 do not.
