BD9D300MUV
4,0 V bis 17 V Eingang, 3 A integrierter MOSFET Single synchroner Abwärts-DC/DC-Wandler
Der BD9D300MUV ist ein synchroner Abwärts-Schaltregler mit integrierten niederohmigen Leistungs-MOSFETs. Diese integrierte Schaltung (IC) ist in der Lage, Strom bis zu 3 A zu liefern. Sie arbeitet mit hoher Schwingfrequenz und geringer Induktivität. Sie verfügt über ein einzigartiges Zeitsteuerungssystem, das bei geringer Last einen niedrigen Stromverbrauch gewährleisten kann. Dieser IC ist ideal, um den Stromverbrauch von Geräten im Standby-Modus zu reduzieren.
