With 4.5-29 V operating range, Model SP7600 can support most retail and architectural lighting systems that use 12 or 24 V power sources. Single chip switching buck LED driver comes with integrated 100 mW MOSFET in thermally enhanced SO-8 package. It supports PWM dimming up to 1 kHz as well as analog dimming, and features 1.2 MHz operating frequency, minimum on-time of 100 nsec, and -40 to...
Read More »Boost Controllers support LED lighting and dc/dc conversion.
Used for powering large LED arrays, SP7606 can also be used for dc/dc conversion in boost, flyback, Cuk, and SEPIC configurations. Internally compensated 1.2 MHz boost controller is suitable for driving any number of topologies using low side switch. Output feedback disconnect eliminates leakage path from input source during shutdown so that shutdown current is less than 80 Ã-µA. Contained in...
