hight power LED driver

Posted by: Doodle on Tue, 04/03/2018

I am going to design LED driver with below specifications
Output Power: 320W
Input Voltage: 90V -305Vac, 50/60Hz
Output Current: 8A
Efficiency: >90%
Please suggest suitable Power integration part for the same.
Thanks and Regards,

Hi Doodle,

For this power level of LED Driver, I would recommend the HiperLCS family. It uses LLC Half-Bridge topology with integrated High Power MOSFETs and Drivers. Kindly see the link below where you could download its datasheet. You may select the appropriate device on the Power Table in the datasheet. You would also find some Design Examples on the link; DER-447 maybe a suitable design reference for you.

If you need high Power Factor for your design, you might need to have a PFC front-end converter. I would recommend the HiperPFS-4 family for PFC which you may find on the link below:

I recommend you to use HiperLCS, its damn good, and long time use, Its the best power converter with very high efficiency, I bought it from Coupon codify because it is too expensive in shops, HiperLCS is the best technology ever using higher efficiency converters to provide greater savings in energy consumption. Well, it's totally up to you which one you wanna buy.
