UR3311 SmartPower Enabled Combo Controller for High PF LED Lighting Overview: UR3311 is a high performance AC/DC off-line power supply controller for LED luminaries. The UR3311 combines power factor correction and LED current regulation into one controller. It achieves PF>0.95 and TH<10% for 100-277Vac input voltage range. UR3311 can be designed into an isolated two stage switching power lighting system which includes Boost and Flyback converters. It also can be designed into a non-isolated two stage switching power lighting system which includes Boost and Buck converters. This greatly simplifies customer’s design for different types of lighting applications. A patented SmartPower supply method enabled UR3311 to have fast startup and low IC supply consumption.
