GL8911S

Preliminary GL8911S High Power Factor & Accuracy Constant Current LED Driver Features Built-in 600V Power MOSFET High Power Factor by One Cycle Control Accuracy Constant Current Low BOM Cost Average Current / Fixed Frequency Control LED Open Protection (OVP) LED Short Protection (SCP) Over Current Protection (OCP) Internal OTP Protection Description The GL8911S integrated a 600V power MOSFET and a highly-integrated, low startup current, average current mode, one cycle control PFC and fixed switching frequency PWM controller. These functions enable the LED driver to easily meet the accuracy average LED current and high power factor requirements. The integrated functions also include the LED short protection, open protection, and internal over temperature protection. The COMP pin controls the duty by connected an RC compensation network to ground and forming the closed loop feedback control. To protect the external Application E26/27, T5/T8 LED Lamp Others LED Lighting Applications power MOSFET from being damaged by supply over voltage. The GL8911S improves the performance and reduces the cost of the LED driver. It is a 8-pin SOP-8 package.
