15V/3MHz-Synchron-Abwärtsregler in einem nur 4mm x 4mm großen

QFN-Gehäuse liefert kontinuierlichen Ausgangsstrom bis 2,5A

(PresseBox) (Milpitas, California (USA), )
Der LTC3603 ist ein wirkungsgradstarker 3MHz- Synchron-Abwärtsregler mit Current-Mode-Architektur und konstanter Schaltfrequenz. Der Chip ist in einem 4mm x 4mm großen QFN-Gehäuse oder einem thermisch optimierten MSOP-16- Gehäuse erhältlich und kann Dauer-Ausgangsströme bis zu 2,5A bei Ausgangsspannungen bis hinab zu 0,6V liefern. Der LTC3603 akzeptiert Eingangsspannungen zwischen 4,5V und 15V und ist dadurch eine ideale Lösung für den Betrieb an Zwei-Zellen-Li-Ion-Akkus oder einer 12V-Betriebsspannungsschiene. Die hohe, im Bereich von 300kHz bis 3MHz programmierbare Schaltfrequenz erlaubt die Verwendung winziger, preiswerter Kondensatoren und Induktivitäten.

Der LTC3603 enthält Schalter mit einem RDS(ON) von nur 45mOhm bzw. 85mOhm und erzielt dadurch Wirkungsgrade bis zu 46%.
