BD9B600MUV
2,7 V bis 5,5 V Eingangsleistung, 6,0 A Synchron-Buck-Wandler DC/DC-Wandler mit Integriertem Einzel-MOSFET

BD9B600MUV ist ein synchroner Abwärtsschaltregler mit integrierten Leistungs-MOSFETs mit niedrigem ON-Widerstand. Dieser IC ermöglicht eine Stromstärke von bis zu 6 A und verfügt durch das Steuersystem zur permanenten Einschaltung über ein schnelles Einschwingverhalten. Es verfügt bei geringer Induktivität über eine hohe Schwingungsfrequenz. Dank der innovativen Steuermethode zur permanenten Einschaltung ist auch bei geringer Last ein Betrieb mit geringem Stromverbrauch möglich. Dadurch ist das Produkt optimal für Ausrüstung und Geräte geeignet, für die ein minimaler Standby-Stromverbrauch erforderlich ist.
