DC DC FOR POWER LED WITH MICROPROCESSOR DIMMABLE

Posted by: K Rahul on 04/12/2012

HELLO TEAM PI,

Greetings!!!

We are looking for constant current led driver which must have following specification:

Input voltage range : 22 to 25 volt dc
Output voltage : 5W to 15W with constant current 350mA
Efficiency : 85% to 90%
Dimmable with Microprocessor

Please suggest me corresponding IC and design resource available.

Regards
Rahul

Hi Rahul,
We do not have a solution for 24V input DC LED controller. PI LED devices are focused on AC to DC applications.

Thanks for asking.

I was using DPA switches with level dim.

Hi Brano,
For better efficiency it's good to configure the circuit for non-isolated.
We can design it as a buck converter.

Please advise if we can use non-isolated approach.
