LM3450 LED Driver

Hi Arik,

The LM3450 is designed to primarily regulate current in the LED. So voltage can be thought of as an independent variable. We may be able to come up with some means to make this a constant voltage regulator, but and easier approach might be to use our UCC287000. What is your load current for each voltage?

Regards,

Hi John,

The load current 4A for 24V and 8A for 12V, so output wattage 100W.

Thank you,
Arik.

HI Arik,

I am checking with the design team to see what options we have for you.

Hi John,

Can't wait to test it.

Thank you,
Arik.

Hi John,

We've developed additional schematic for CV LED driver, it's work good ( we still testing on 30W board).

The problem is that it dims down to 15-20% of the max. light and customers want much lower as 1-2%. How can I extend the dimming?

Please email me to techsupport@emcod.com

Thank you,

Arik.
