Survey of TI device application in fill light

The LM3434 can do it. There is an EVM for the LM3433 that can already do 33A. But it would probably need some heatsinks glued to the FETs if it is continuous. If it is just a pulse application where it is off most of the time no problem. The LM3434 is pin for pin compatible with the LM3433. I just always suggest it because they are identical except the LM3434 has a higher input voltage rating and almost double the gate drive current capability.

Dear Sir,

Thanks for you reply.
