Pololu 9V Step-Up Step-Down Spannungsregler S10V3F9

Artikelnummer: PO2095

Hersteller Artikel Nr.: 2095

This switching regulator uses the SEPIC topology to produce 9V from input voltages between 2.5V and 18V. The wide input range coupled with 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 9V. The compact (0.4"x0.575") module can supply over 300mA in typical applications.

Overview

The Pololu step-up/step-down voltage regulator S10V3F9 is a switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) with a single-ended primary-inductor converter (SEPIC) topology. It takes an input voltage from 2.5 V to 18 V and increases or decreases the voltage to a fixed 9 V output with a typical efficiency of 70% to 80%.

This flexibility in input voltage is especially well-suited for battery-powered applications in which the battery voltage begins above 9 V and drops below as the battery discharges. Since it lacks the typical restriction that the battery voltage stay above the required voltage throughout its life, new battery packs and form factors can be considered. For instance, a 7-cell battery holder, which might have an 11 V output with fresh alkalines but an 8.4 V nominal voltage with NiMH cells and a 7 V output with partially discharged cells, can now be used to produce a steady 9 V output.

In typical applications, this regulator can deliver over 300 mA continuous; please see the graphs at the bottom of this page for a more detailed characterization. The regulator?s thermal shutdown prevents damage from overheating, but it does nothave short-circuit or reverse-voltage protection.

This regulator is also available with a fixed 5 V output or a fixed 12 V output.

Features

  • Input voltage: 2.5 V to 18 V (can be higher than, the same as, or lower than the 9 V output)
  • Fixed 9 V output with 4% accuracy
  • Typical continuous output current: 300 mA (actual continuous output current depends on input voltage; see Typical Efficiency and Output Current section below for details)
  • <2 mA typical no-load quiescent current
  • Integrated over-temperature shutoff
  • Small size: 0.40" × 0.575" × 0.1" (10 mm × 15 mm × 3 mm)
