Induktivitätsloser Multi-Mode-LED-Treiber mit nur 6mm2 Grundfläche liefert 400mA

(PresseBox) (Milpitas, California (USA), )
Linear Technology Corporation präsentiert den LTC3218, einen induktivitätslosen Hochstrom-Weißlicht-LED-Treiber, der Ströme bis zu 400mA liefern kann. Der Chip hat eine Multi-Mode-Architektur, die die Spannung über der LED-Stromquelle überwacht und automatisch zwischen 1x- oder 2x-Boost-Modus umschaltet, wenn ein ILED-Dropout erkannt wird. Der LTC3218 enthält einen High-Side-Strommesswiderstand zur Regelung des LED-Stroms. Dadurch wird die Dropout-Spannung niedrig gehalten und der Chip kann länger im 1x-Modus verbleiben. Dies maximiert den Wirkungsgrad über den vollen Li-Ion/Polymer-Batterie-Spannungsbereich, verlängert die Batterielaufzeit und minimiert das Rauschen. Der LTC3218 liefert einen gepulsten Strom bis zu 400mA für Kamerablitze oder einen Dauerstrom bis zu 150mA für Kamerahilfslichter. Der Chip lässt qzpw jttz bthxt oaanewxl Nmnsvbsqeo yquzkztwyceqa.
