90-305 Vac, 0.8 Power Factor, 8 W LED Driver Evaluation Board

Overview

The NCP1014GTGEVB Greenpoint(TM) reference design board has been specifically designed to meet the > 0.7 power factor requirements of residential Energy Star(R) LED Luminaires without the addition of extra circuitry. This makes the driver an ideal candidate for products such as portable desk lamps, step lights, and undercabinet lighting that are included in the Energy Star residential product category. This design is rated at 8W which makes it ideal for driving devices like the Cree XLAMP(R) MC-E which integrates 4 LEDs in single package. The current for this evaluation board is set at 630 mA nominal although the current can be changed to other values by modifying a current setting sense resistor. While the power factor (>0.8 nominal) has been optimized for AC inputs in the range of 90 - 135 Vac , the board supports an AC input range of 90-265 V ac. While not populated, there are provisions in the board layout to support an optional analog dimming circuit which may be attractive for some applications. It contains all necessary features such as soft-start, frequency jittering, skip cycle etc. to build a rugged and low cost power supply. The device has dynamic self supply to allow it to be powered directly from the high voltage bulk. This demo board uses an auxiliary winding to maximize power output capability.
