The efficiency is the tallest in the world, the service life grows most of off-line type LED the manufacturer of the actuator IC Power Integrations the company released a style of new reference design(DER-297) today, is the high-efficiency and super tightly packed actuator that aims at a LED lamp bulb design.That power doesn't insulate single LED according to the LinkSwitch-PL of Power Integrations series actuator IC design but become, specially be applicable to a high pressure LED application, for example Cree release recently of XLamp XM-L and XLamp the XT-E series LED product.DER-297 can provide the high pressure that the LED requests to output, and pass to lower to drive electricity and the achievement that the electric current in the exportation diode results in to consume to promote a whole system efficiency.
The power DER-297 designed to all amount to use 20 components, physical volume smallest, the cost efficiency shows Zhao very much.The LinkSwitch-PL spare part has the highest integration degree, it is single to decline to press in one-rose to press to integrate PFC and Heng to flow function in the electric circuit.For LED of a 4.3 Ws actuator, that design the efficiency can attain 87%(can reach to 86% for 2.9 W outputting an efficiency) under the 115 VAC, in the meantime power factor over 0.9, can easily satisfy EN61000-3-2 like this Class C limit the value requests and make the total Xie wave lost to be really(THD) lower than 20%.
Power Integrations is responsible for the product marketing that LED applies business manager Andrew Smith mean:"The lighting application of small scaled B10 lamp bulbs and same shape tightly packeds puts forward a tremendous challenge for LED light.In DER-297 LinkSwitch-PL of the usage spare part since can let up an actuator physical volume, can raise its work efficiency again, therefore we have never needed to adopt to infuse to note compound or sacrifice its function, can immediately pack the design into a B10 light.The material detailed list(BOM) of simplifying also means that converting the cost of machine is the lowest and makes the price competed day by day a vigorous lighting market."
The applied engineering of the Cree company supervisor Mark McClear add to say:"The B10 lamp bulb outer shell physical volume broughts a very tough engineering challenges for designer of actuator smallest.The LinkSwitch-PL spare part adoption of Power Integrations declines to press-rise a press type the Tuo rush toward structure, not only can provide for LED smooth drive, and return an ability the number and high work efficiency easily satisfy a low component various physics and spread a hot norm request."
