BD9P233MUF-C
3,0V bis 36V Eingang, 2,0A Integrierter FET Single-Synchron-Ruhestrom-DC/DC-Abwärtswandler für die Automobilindustrie.

Der BD9P233MUF-C ist ein Abwärtswandler mit extrem niedrigem IQ und 3,3V Ausgangsspannung. Die LLM-Steuerung (Light Load Mode) sorgt für einen extrem niedrigen Ruhestrom und einen hohen Wirkungsgrad sowohl bei geringer als auch bei hoher Last, wobei die Ausgangsspannung geregelt bleibt.
