BD9S300MUF-C
2,7V bis 5,5V Eingang, 3A integrierter synchroner MOSFET-Abwärts-Gleichspannungswandler für die Automobilindustrie

Der BD9S300MUF-C ist ein synchroner DC/DC-Abwärtswandler mit integrierten Leistungs-MOSFETs mit niedrigem Durchlasswiderstand. Es kann Strom bis zu 3A liefern. Die SLLM™ Steuerung bietet hervorragende Effizienzeigenschaften bei leichter Last, was das Produkt ideal zur Reduzierung des Standby-Stromverbrauchs von Geräten macht. Durch die hohe Schaltfrequenz von 2,2MHz kann eine kleine Induktivität eingesetzt werden. Es handelt sich um einen DC/DC-Wandler mit Stromregelung, der sich durch ein schnelles Einschwingverhalten auszeichnet. Auch die Phasenkompensation lässt sich leicht einstellen. Er kann auch auf externe Impulse synchronisiert werden.
