2,7-4,5 V 0,8 A 1-Kanal-Inverswandler - BD9120HFN

ROHM's höchst effizienter Zweikanal-Abwärts-Schaltregler (BD91??) ist ein Netzteil, das für Niederspannung von 1 Volt bei 5 / 3,3 Volt Schaltkreisen gemacht wurde. Höchst effizient dank unserer Impuls-Sprung-Steuerungs-Technologie und unseres synchronen Gleichrichters. Setzt ein Steuersystem mit Strommodus ein, um ein schnelles Einschwingverhalten bei plötzlichen Lastveränderungen zu garantieren.

* Dieses Produkt entspricht der STANDARD-Güte und wird nicht für Fahrzeugteile empfohlen.
