Overview
Preliminary GL8212 High Power Factor & Accuracy Constant Current LED Driver Features          TM (Transition Mode) Fixed On -Time PFC Control Accuracy Constant Current Low BOM Cost Inductor Size Reduction CT Pin Adjust Frequency Range for Optimization Over Voltage Protection (OVP)-Auto Recovery LED Short Protection (SCP) -Auto Recovery Over Load Protection (OLP) -Auto Recovery SOT-26 Package Description The GL8212 is a highly-integrated, low startup current, TM (Transition Mode), fixed on- time PFC control and 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, over voltage protection, over load protection.
The COMP pin controls the duty by connected an RC compensation network to ground and forming the closed loop feedback control.
The GL8212 improves the performance and reduces the cost of the LED driver.
It is a 6-pin SOT-26 package.
