Optimal Power Design GP8653140 High Power Factor & Accuracy Constant Current LED Driver Description The GP8634 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 GP8634 integrates a power MOSFET with 600V breakdown voltage. 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. The GP8634 improves the performance and reduces the cost of the LED driver.
