Universal-LED-Treiber

360mA Ausgangsstrom, unabhängige Ansteuerung von bis zu 18 LEDs, geringes Schaltrauschen, bis zu 91% Wirkungsgrad

(PresseBox) (Milpitas, California (USA), )
Linear Technology Corporation präsentiert den LTC3220/-1, einen wirkungsgradstarken LED-Treiber für Mobiltelefon-Displays und sonstige programmierbare Beleuchtungsanwendungen, der ohne Induktivität auskommt und wenig Störstrahlung produziert. Das neue IC enthält 18 indivi-duell konfigurierbare LED-Stromquellen und bietet dadurch höchste Flexibilität bei der Program-mierung mehrerer Displays. Die Display-Ströme werden über eine hochgenaue interne Stromrefe-renz eingestellt. Folgende Parameter der universellen Stromquellen können individuell über eine einfache serielle Zweidraht-I2C-Schnittstelle digital gesteuert werden: Dimmen, Helligkeit, Blinken und Gradation. Die Chips LTC3220 und LTC3220-1 haben unterschiedliche I2C-Adressen. Der Eingangsspannungsbereich des LTC3220/-1 (2,9V bis 5,5V) wurde für Geräte opti-miert, die durch eine Ein-Zellen-Li-Ion/Polymer-Batterie gespeist werden.
