Allegro offers a variety of highly integrated LED drivers for backlighting to match your requirements for input voltage range, number of LEDs per string, number of strings and LED current. Our LED drivers lead the industry in reliability and robustness, with AEC-Q100 Grade 0 qualification, operation to 150°C, protection against pin-to-pin shorts and open/shorted external components, and built-in fault diagnostic capabilities.
Patented control technologies enable industry-leading LED dimming range performance as well as compliance to challenging input voltage transients, such as automotive idle-stop and load dump. Fast/controlled startup allows customers to minimize time-to-light, not just as a convenience for infotainment applications but also for safety in concert with back-up cameras.
We also provide proven EMC reference designs tested in our in-house EMC laboratory to ensure successful and rapid EMC compliance. Plus, our field is well trained and ready to support your projects at the local level.
The ALT80600 is a multi-output LED driver for small-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and four current sinks.
The A80601 and A80604 are high power LED drivers that feature pre-emptive boost for ultra-high dimming with low output ripple and avoidance of audible noises.
