ISL1904 NOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc Dimmable AC Mains LED Driver with PFC and Primary Side Regulation DATASHEET FN8286 Rev 1.00 September 20, 2012 The ISL1904 is a high-performance, critical conduction mode (CrCM), flyback controller used for single-stage conversion of the AC mains to a constant current source with power factor correction (PFC).
The controller regulates the output current by monitoring the primary side switching current so the feedback signal does not cross the isolation barrier.
Operation in CrCM allows near zero-voltage quasi-resonant switching (ZVS) for improved efficiency while maximizing magnetic core utilization.
