24V, 500 mA LED Driver

Posted by: EP-INDIA on 06/02/2022

Hello Team,

We are working on to design 24 V constant voltage output for driving LED String. We are using VAC - 110 VAC to 230 VAC.  We can go with Isolated and non-isolated both architecture, as per availabilty of design. Please share proper part s and reference design.

Hello,

We have a DER that you can use as a reference design for your application here: https://www.power.com/sites/default/files/documents/der-630_12watt_high-efficiency-and-pf_isolated_flyback_for_smart_lighting_using_lytswitch-6…

In order to tweak it to your specifications some changes need to be made, namely the values of R8 and R9 for the required voltage level and R10 for the required current.
