BD9A100MUV
2,7 V bis 5,5 V Eingangsleistung, 1 A Synchron-Buck-Wandler DC/DC-Wandler mit Integriertem Einzel-MOSFET

BD9A100MUV ist ein synchroner Abwärtsschaltregler mit integrierten Leistungs-MOSFETs mit niedrigem ON-Widerstand. Eine Stromstärke von bis zu 1 A ist möglich. Durch die SLLM™-Steuerung kann bei geringer Last eine hohe Effizienz erreicht werden. Dadurch ist das Produkt optimal für Ausrüstung und Geräte geeignet, für die ein minimaler Standby-Stromverbrauch erforderlich ist. Die Schwingungsfrequenz liegt mit 1 MHz hoch und weist einen kleinen Induktanzwert auf. Der DC/DC-Wandler zur Steuerung des Strommodus zeichnet sich durch ein Hochgeschwindigkeitseinschwingverhalten aus. Auch die Phasenkompensation ist leicht einstellbar.
