The S13V30F5 switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) uses a buck-boost topology to convert both higher and lower input voltages to a regulated 5 V output. It takes input voltages from 2.8 V to 22 V and increases or decreases them as necessary, offering a typical efficiency of over 85% and a typical output current of 3 A.
The flexibility in input voltage 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 regulator has input reverse voltage protection up to 20 V, 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.
