Pololu S9V11F5 switching step-up/step-down regulatoren producerer effektivt 5V fra indgangsspændinger mellem 2V og 16V ( Bemærk: den kræver en indgangsspænding på mindst 3V for at starte, men den kan fungere ned til 2V efter opstart ).

Dens evne til at konvertere både højere og lavere indgangsspændinger gør den nyttig til applikationer, hvor strømforsyningsspændingen kan variere meget, som f.eks. med batterier, der starter over, men aflades under 5V. Det meget kompakte (7,6 × 11,4 × 3,8 mm) modul har en typisk effektivitet på over 90% og kan levere en typisk udgangsstrøm på op til 1,5A, når indgangsspændingen er omkring 5V.

Bemærk: Under normal drift kan dette produkt blive så varmt, at du kan blive forbrændt. Vær forsigtig, når du håndterer dette produkt eller andre komponenter, der er tilsluttet det.

S9V11x-familien

S9V11x-familien af effektive switchingregulatorer (også kaldet switched-mode strømforsyninger (SMPS) eller DC-til-DC-konvertere) bruger en buck-boost-topologi til at konvertere både højere og lavere indgangsspændinger til en reguleret udgangsspænding. De tager indgangsspændinger fra 2 V til 16 V og øger eller mindsker dem efter behov, hvilket giver en typisk effektivitet på over 85 % og en typisk udgangsstrøm på op til 1,5 A.

Den fleksibilitet i indgangsspænding, som denne familie af regulatorer tilbyder, er særligt velegnet til batteridrevne applikationer, hvor batterispændingen begynder over den regulerede spænding og falder under, når batteriet aflades. Uden den typiske begrænsning af, at batterispændingen skal forblive over den krævede spænding i hele batteriets levetid, kan nye batteripakker og formfaktorer overvejes.

De forskellige medlemmer af denne familie tilbyder forskellige udgangsspændingsmuligheder, fra faste spændinger med valgbare alternativer til justerbare spændinger, der kan indstilles hvor som helst mellem 2,5 V og 9 V ved hjælp af et præcisionspotentiometer med 12 omdrejninger. Nogle versioner har også en justerbar lavspændingsafbryder, der kan indstilles hvor som helst i udgangsspændingsområdet fra 2 V til 16 V og bruges til at forhindre, at dit batteri overaflades. Dette er især nyttigt til batterikemi, der kan blive beskadiget ved overafladelse, herunder Li-ion og LiPo.

Disse regulatorer har kortslutningsbeskyttelse, og termisk nedlukning forhindrer skader forårsaget af overophedning; de har ikke beskyttelse mod omvendt spænding. Bemærk, at opstartsstrømmen er begrænset til cirka 700 mA, indtil udgangsspændingen når den nominelle spænding; efter opstart er den tilgængelige strøm en funktion af indgangsspændingen (se afsnittet Typisk virkningsgrad og udgangsstrøm nedenfor).

Funktioner

  • Indgangsspænding: 2 V til 16 V (bemærk: denne regulator kræver 3 V for at starte, men den kan fungere ned til 2 V efter opstart)
  • Fast 5 V udgang med +5/-3% nøjagtighed
  • Typisk maksimal kontinuerlig udgangsstrøm: 1,5 A (når indgangsspændingen er omkring 5 V; afsnittet Typisk effektivitet og udgangsstrøm nedenfor viser, hvordan den opnåelige kontinuerlige udgangsstrøm afhænger af indgangsspændingen)
  • Strømbesparende funktion opretholder høj effektivitet ved lave strømme (hvilestrømmen er mindre end 0,2 mA)
  • Integreret overtemperatur- og kortslutningsbeskyttelse
  • Lille størrelse: 7,6 × 11,4 × 3,8 mm
