Looking for Led Driver for 100w 33v 3a led from a 11-14 volt source (automotive)

Source in 11-15 volts (automotive, 12v nominal) 

Led is 100Watt, 33Volt 3amp (32-34volts)

I've searched all over the place, the LT3762 Seems to only do 30v 2amp

Any suggestions?

    In theory, the LT3761 can deliver this power level from an automotive input range, however things may get hot during operation. The difference between the LT3761 and the LT3762 is that the LT3762 uses a synchronous switching scheme, unlike the LT3761. Synchronous switching will result in a much more efficient solution with less heat dissipation through the switching elements. If heat and losses are a concern, then I would recommend using the LT3762.
