1 High Voltage Constant Current Linear Regulator LED Driver Features Low Quiescent Current Need not Inductor Component Programmable LED Current Over Temperature Protection RoHS Compliant and 100% Lead (Pb)-Free and Green (Halogen Free with Commercial Standard) General Description The ORG8510 is capable of driving multiple series connected LEDs. ORG8510is a high voltage process chip with internal regulator to generate bios voltage which supports IC internal circuit. The ORG8510 also has internal power switch to minimize external components. The ORG8510 consists of Iset pin to set LEDs constant current level.the ORG8510 also has over temperature function to protect IC. The package of ORG8510 is SOT-25. Which suitable for LED lighting like MR-16, E17, E27 and so on applications. Applications LED MR16 and general lighting LED E17, E26, E27 lighting LED Lamp lighting Simplified Application Circuit L AC N AC Cin Q1 C1 Rcs Page: 1/7

These are stress ratings only, and function operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum -rated conditions for extended periods may affect device reliability. *Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the recommended operating conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. Page: 3/7
