Fairchild Semiconductor Corp. during Electronica announced the FL7733A Single Stage Primary-Side-Regulated (PSR) Flyback LED Driver for delivering constant brightness and instant flicker-free turn-on of LED lighting. The new low-power LED lighting driver is built for a variety of 5W to over 60W, indoor and outdoor LED applications so that designers can easily overcome the challenge of meeting global standards and regulations for LED lighting with a single, scalable solution.

“Fairchild’s new FL7733A solves the major challenge customers have for LED applications that need to meet space and cost restrictions over a wide output voltage range,” said Preet Sibia, Fairchild’s Director Product Marketing. “The FL7733A driver has tight constant current regulation and excellent PF/THD performance so designs can easily meet the many different requirements of the different regional markets our customers ship to.”

The best-in-class THD of less than 10% at universal line voltage conditions is significantly less that the 30% THD that makes up most regional regulations. This gives designers plenty of headroom to scale product offerings for various regions of the world. In addition, the FL7733A uses dual over voltage protection (OVP) to meet UL SELV under 60 V output regulations.
