Hey everyone,

I am currently searching for a dimmable LED Driver with at least 1A total output current and 30V or more max Vin.
As I want to output the have as low ripple as possible I had a look at the Texas Instruments TPS92200D2.
It can convert digital/PWM input to an analog output.
It is almost perfect however the adjustable range is only 1%-100% duty cycle.

This I might be able to solve with a more complicated setup but the best thing would be to have a comparable Driver with a higher adjustable range.
Do you guys know a LED Driver similar to the TPS92200D2 but with a higher dimming range (e.g. 0,1%-100%)?

Best wishes,
Jordi

 

however the adjustable range is only 1%-100% duty cycle.

There is probably a reason for that. I doubt that you will find a ready-made solution that can do a wider range because almost no one would require it.

 

How much visible output do you expect with a 1% duty-cycle?

Let alone 0.1%. But we do not know what he is expecting to do with this, it.
