BD9G341AEFJ-LB
1-Kanal Buck-Wandler Integrierter FET

Für das Produkt wird ein Langzeit-Support im industriellen Markt garantiert. Der BD9G341AEFJ-LB ist ein Abwärtsschaltregler mit eingebautem 150mΩ Leistungs-MOSFET. Strommodusarchitektur liefert eine schnelle Einschwingcharakteristik und eine einfaches Einrichten der Phasenkompensation. Die Betriebsfrequenz ist programmierbar von 50 bis 750 kHz. Es sind zusätzliche Schutzfunktionen vorhanden wie Überstromschutz, thermische Abschaltung und Unterspannungssperre. Die Unterspannungssperre und Hysterese können von einem externen Widerstand festgelegt werden.
