36V-Abwärtsregler-LED-Treiber mit 3000:1-True-Color-PWM-Dimmer liefert Ausgangsströme bis 1,5A pro Kanal

(PresseBox) (Heilbronn, )
Milpitas, California (USA) - 1. Juni 2006. Linear Technology Corporation präsentiert den LT3475, einen Zweifach-36V-Gleichspannungs-Abwärtswandler für Schaltfrequenzen bis zu 2MHz, der für den Einsatz als Zweikanal LED-Konstantstromtreiber vorgesehen ist. Jeder Kanal enthält einen integrierten Strommesswiderstand und eine Dimmerschaltung. Der Chip eignet sich dadurch bestens als Treiber für LEDs mit einem maximalen Betriebsstrom von 1,5A. Die beiden Kanäle schalten mit einer Phasenverschiebung von 180 Grad; dadurch verringert sich die Eingangsstromwelligkeit. Beide Kanäle bieten eine hohe Ausgangsstromgenauigkeit über einen weiten Bereich von 50mA bis 1,5A. Die einzigartige True-Color-PWMTM-Schaltung ermöglicht es, die angeschlossene LED über einen Bereich von 3000:1 zu dimmen, ohne dass zsgv Gqrdyjrikqlkslgi prxfochy, vsz vhx kbd qzf icsdbpyfyuknz OCT-Igrvvmh kzfsh.
