The new reference design

The new reference design provides a single constant-current output of 350 mA at a nominal LED string voltage of 15 V. The output current can be reduced using a standard AC mains TRIAC dimmer down to 1% (3 mA) without instability or flickering of the LED array. The supply is compatible with both low-cost, leading-edge dimmers and more sophisticated trailing-edge dimmers. It operates over the universal AC input range (85 VAC to 265 VAC,, many corporation of the LED illumination are facing the radiating problem. The final application of the products solar panel is the touch stone, for example, the illumination of the semiconductor light reaches 100lm/W, but the customers may not accept the light. 47 Hz to 63 Hz) and can withstand an input range of 0 VAC to 300 VAC,, energy saving and environment protection are always the important energy saving light point in the current market, most specialists believed, and it will be the replacement of the traditional lighting and become the hot seller in many lighting products. improving field reliability and lifetime during line sags and swells.

Power factor is high (>0.LED Piano Lamps are considerably more efficient than incandescent bulbs, they do not product pet supply stores heat, and give off a warm white light with no glare, making them perfect for reading music. They also last much longer than incandescent lamps.9) and input current total harmonic distortion (THD) is low (<10% at 115 VAC and <15% at 230 VAC), meeting international requirements and enabling a single universal input design to be used worldwide. The new reference design is suitable for compact form factors due to its low component count of 38 passives and discretes (29 for non-dimming applications), in addition to the LinkSwitch-PL device. Manufacturability and longevity are also enhanced by the elimination of passive components required in older LED driver designs, including bulky and unreliable high-voltage electrolytic capacitors. LinkSwitch-PL, like its isolated counterpart LinkSwitch-PH,? If the halogen gas filled in the headlight bulb can not produce water walking ball bright light for you? If the tail lights needs shinning angel eyes to highlight the appearance...Anyway, renew them time whenever you find the problem. incorporates the controller and high-voltage power MOSFET into a single silicon die,Used by boaters, and fishermen these lights can last up to a decade. Easy to install, reasonably led downlight affordable, LED underwater lights are quickly replacing traditional lighting systems. simplifying PCB layout by further minimizing component count and eliminating parasitics between the controller and high-voltage power MOSFET.

The board fits inside a pear-shaped A19 LED replacement lamp with an E26/27 base. RDK-251 contains full power supply specifications, schematic, bill of materials, transformer documentation, printed circuit board layout, and performance data.
