GL8211代理台湾绿达电源管理芯片SOT-26

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 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.
