GP8630A

GP8630A High Power Factor & Accuracy Constant Current LED Driver Built-in MOSFET Description Application The GP8630A 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 GP8630A 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 GP8630A improves the performance and reduces the cost of the LED driver.
