BD9305AFVM
Abwärtswandler, Hochleistungsschaltregler (Typ: Regler)

BD9305AFVM / BD9306AFVM sind 1-Kanal DC / DC Umwandler Controller. Tiefsetzsteller DC / DC können von BD9305AFVM und Aufwärtsregler DC / DC können von BD9306AVFM konfiguriert werden. Zusätzlich ist die Master-Slave-Funktion, wodurch die Synchronisierung bei der Mehrverbindung möglich gemacht wird, angebracht.
