Overview
Preliminary GL8211/11B High Power Factor & Accuracy Constant Current LED Driver Features High Power Factor by One Cycle Control Accuracy Constant Current Low BOM Cost Linear Dimming on DIM Pin Average Current / Fixed Frequency Control Gate Output Voltage Clamp LED Open Protection (OVP) LED Short Protection (SCP) Over Current Protection (OCP) Internal OTP Protection 300mA Driving Capability for OUT Pin Fast Start Current for GL8211B Description The GL8211/11B is 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 power MOSFET from being damaged by supply over voltage, the GL8211/11B OUT pin voltage is Application E26/27, T5/T8 LED Lamp Others LED Lighting Applications clamped to about 15V.
The GL8211/11B improves the performance and reduces the cost of the LED driver.
It is a 6-pin SOT-26 package.
