Overview
G8211/GP8211 High Power Factor & Accuracy Constant Current LED Driver Description Application The G8211 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 G8211 OUT pin voltage is clamped to about 12V.
The G8211 improves the performance and reduces the cost of the LED driver.
