Fremont Micro Devices launched two new application samples for the FT838RNA. The FT838RNA facilitates the design of AC/DC LED driver applications. The LED current can be accurately regulated by sensing the primary side information with a few external components without the need for an opto-coupler and TL431. The integrated low voltage lockout and built-in cable compensation functions can lower the cost and increase the efficiency, in order to offer consumers the more affordable LED lighting products. “The two new FT838RNA application examples enab...
