Vierfach-LED-Treiber für bis 32 1A-LEDs ermög¬licht True-Color-PWMTM-Dimmen bis 1000:1

(PresseBox) (Milpitas, California (USA), )
Linear Technology Corporation präsentiert den LT3476, einen 2MHz-Gleichspannungswandler, der als Vierkanal-Konstantstromtreiber für LEDs vorgesehen ist. Jeder Kanal des LT3476 kann bis zu acht in Serie geschaltete 1A-LEDs treiben, das sind pro Chip bis zu 32 1A-LEDs, und dies mit Wirkungsgraden bis zu 96%. Jeder der vier Kanäle wird durch ein unabhängiges True-Color-PWM-Signal gesteuert. Dadurch ist es möglich, die Kanäle individuell bis zu Faktor 1000:1 zu dimmen. Der Chip basiert auf einer Current-Mode-Architektur mit fester Schaltfrequenz und arbeitet dadurch stabil über einen weiten Bereich von Ein- und Ausgangsspannungen. Die Schaltfrequenz kann über einen dafür vorgesehenen Anschluss im Bereich von 200kHz bis
