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.
