ROHM Product Detail

BD81A76EFV-M
6-Kanal-Treiber für weiße LEDs Eingebauter Stromtreiber Auf-/Abwärts-DC/DC-Wandler für Automobilanwendungen

BD81A76EFV-M ist ein Treiber für weiße LEDs mit der Fähigkeit, einer hohen Eingangsspannung (maximal 35 V) standzuhalten. Dieser Treiber verfügt über 6-Kanal-Konstantstromtreiber in einem Chip, wobei jeder Kanal bis zu 120 mA (Max.) aufnehmen kann, und er ist für leuchtstarke LEDs geeignet. Darüber hinaus ist auch ein DC/DC-Wandler mit Aufwärts-/Abwärts-Modus eingebaut, um einen stabilen Betrieb bei Spannungsschwankungen zu erreichen. Über den PWM-Eingang ist eine Lichtmodulation (10.000:1@100 Hz Dimmfunktion) möglich.
