Dreikanal-LED-Treiber kann bis zu 24 500mA-LEDs ansteuern und ermöglicht True-Color-PWM-Dimming im Verhältnis bis 3.000:1

(PresseBox) (Ismaning, )
Linear Technology Corporation präsentiert den LT3496, einen 2MHz-Gleichspannungswandler, der für den Einsatz als Dreikanal-Konstantstrom-LED-Treiber vorgesehen ist. Jeder der drei Kanäle des LT3496 kann bis zu acht in Serie geschaltete 500mA-LEDs treiben; insgesamt kann der Chip also bis zu 24 500mA-LEDs treiben, und das mit einem Wirkungsgrad bis zu 96%. Alle drei Kanäle können unabhängig voneinander mittels eines True-Color-PWM™-Signals über einen großen Bereich von 3.000:1 gedimmt werden. Die feste Schaltfrequenz und die Current-Mode-Architektur gewährleisten einen stabilen Betrieb über einen weiten Ein- und Ausgangsspannungsbereich. Über einen Frequenz-Programmieranschluss kann zwischen 330kHz und 2,1MHz Schaltfrequenz gewählt werden; so kann der Wirkungsgrad optimiert werden, und vk qhrnjm uzca iopgcz zeppjoe Cepaurgy qhuqxzqds xmfbbs.
