Mind looking at LT3762? This IC has the closes features that you are looking for.
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…
We are looking at using the LT3762 to drive an LED as a flash for photography. The LED will be off for essentially all the time and be on for a 50ms flash. But when it comes on, the LED needs to have a rise time of 100us. It seems that using the EN/UVLO…
The LT3762 looks like a nice part with the synchronous swing switch option! However, the datasheet for the LT3762 is still at Rev 0 and provides little guidance for options with the "Lpwr" INTVcc inductor. From the part block diagram, it looks…
The LT3518 is not designed for short-circuit protection.
More recent ICs such as the LT3922, LT3795, LT3762, LT3932, LT8391A and other LED drivers now have the short-circuit protection which you are looking for.
I hope this helps,
Is it possible to use for LT3762 VIN a voltage supply that is lower than the main input voltage of the boost converter?
I have the successful LTSpice simulation but the live circuit stood working for a few seconds only, from an external…
I see that you are looking for an LED driver with these specs...
input voltage from 3v to 18v and a 12v and 2.1A output
This clearly requires one form or another of a buck-boost topology.
The LT8391 is a great buck-boost to use (with…
