BD9B300MUV
2,7 V bis 5,5 V Eingang, 3,0 A Abwärts-DC/DC-Wandler mit integriertem MOSFET

Der BD9B300MUV ist ein synchroner DC/DC-Abwärtsschaltregler mit integrierten Leistungs-MOSFETs mit niedrigem Durchlasswiderstand. Dieser IC, der in der Lage ist, einen Strom von bis zu 3 A zu liefern, zeichnet sich durch schnelles Einschwingverhalten aus, indem er ein Steuerungssystem mit konstanter Einschaltdauer verwendet. Er bietet eine hohe Schaltfrequenz bei niedriger Induktivität. Mit seiner einzigartigen konstanten Einschaltdauer-Steuerungsmethode, die bei geringer Last mit geringem Verbrauch arbeitet, eignet sich dieses Produkt ideal für Geräte und Einrichtungen, die einen minimalen Standby-Stromverbrauch erfordern.
