Beschreibung
The 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 offered by this family of regulators is especially well-suited for battery-powered applications in which the battery voltage begins above the regulated voltage 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 S13V25Fx regulators have under-voltage lockout, output over-voltage protection, over-current protection, and reverse-voltage protection up to 20 V. 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.
This family consists of six 2.5 A regulators with output voltages ranging from 3.3 V to 15 V. These all use the same PCB with different components populated to achieve the different output voltages:
