1 / 1 page ![]() XD9057 Ver 1.0 June 2014 1 XD9057 High Voltage LED Lighting Driver DESCRIPTION XD9057 is an LED driver with high voltage switches which can be powered directly from the 110V/220V AC Mains. With the internal dual negative feedback mechanism, the average current of the LED does not vary with changes in external parameters like temperature and the input voltage. It performances high PF, high efficiency, and extra low EMI spikes at the same time. The output power can be adjusted by an external resistor. XD9057 features high-precision zero temperature coefficient of the reference voltage, over voltage protection, over temperature protection, under voltage lockout and other functions. It has significant advantages in the applications of tube light, ceiling light, and etc.. FEATURES Driven directly from AC lines, power 7W-15W LED. High performance in Power factor (>0.95) with high efficiency. Optimized EMI characteristics eliminate additional EMI filter components. Zero temperature coefficients LED current. Special feedback mechanisms keep the luminance of LED stable in ± 10% (RMS) AC voltage tolerance. Output power adjustable by sole external resistor. Over voltage / Over temperature protection, under voltage lock-out. Built-in analog dimming function Better heat sink capacity and high-reliability for the TSSOP-16 (EP) package. RoHS compliant and 100% lead (Pb) free Halogen free. Typical Application Circuit Figure. 1 Typical Application Diagram |
