GL8259

GL8259 Primary side control off line LED controller with active PFC Preliminary Features  General Description The GL8259 is a single-power stage, isolated, primary side control offline LED lighting controller that achieves high power factor.The proprietary real-current control method can control the LED current accurately from the primary side information. It can significantly simplify the LED lighting system design by eliminating the secondary side feedback components and the optocoupler. The extremely low start-up current and quiescent current reduces the total power consumption to provide a high efficiency solution for lighting applications. The multi-protection features of GL8259 greatly enhance the system reliability and safety. The GL8259 features over voltage protection, short circuit protection, cycle-by-cycle current limit, auto restart over temperature protection Real-Current Control Without SecondaryFeedback           Accurate Constant Current Output Transition Mode (TM) PFC Control Ultra-Low (10µA) Start Up Current Low (1mA) Quiescent Current Over-Temperature Protection Cycle-by-Cycle Over Current Protection VCC Pin Over Voltage Protection Output Open Protection Short-Circuit Protection Available in SOT26 Package Application    Solid State Lighting Industrial and Commercial Lighting Residential Lighting Typical application 2012.03 Ver.
