[ Reading] Mid-range entry-level LED lighting lamps and lanterns market finally enter the grace wisdom pu semiconductor ( NXP) Maturing, the recent fall in HK lighting before opening, NXP 5 for entry-level LED lighting market drive and the isolation constant-current power supply reference solution, the price is low, but the performance so unambiguous.

panasonic LED lighting 'EVERLEDS' series product range of lighting as incandescent bulbs Japan LED the size of the market to expand quickly soared nearly 2 times

‍ end of October 2014, NXP relief launched five low-cost entry-level grid dimmer and dimmer LED drive, supporting the dimming applications is SSL5021B and SSL5031B, support the dimming applications SSL5231, SSL5236 and SSL5237, this paragraph 5 entry-level LED driver is only six feet TSOP package IC, based on its development of constant current drive power supply can meet the LED candle light and GU10 lamp base size requirements. In general, the 5 product support LED lighting lamps and lanterns power output in the range of 2 - 25W。

SSL5021B is below 10 w minimum ripple, the lowest cost of LED candle light and alternative type of ball steep light not isolation, not the light solution, low ripple below 3% ( 100 hz and 120 hz) No stroboscopic, truly. The output precision of constant current is less than 3%, 90 - 305 vac mains input, support the shield inductance, driving triode or MOSFET switch, the power efficiency is up more than 90%, the output voltage can be from 40 v to 88 v, peripheral only need 12 the following components, easy to implement the single side PCB board design, support all protection function, can from - working temperature 40 degrees to + 105 degrees. The only is less than PF only to 0. Five or so, but it's already can meet most of the market demand for under 6 watt LED lamps and lanterns.

SSL5031B 10 w - is the requirement of high values of PF 20 w T torch, LED downlight and alternative type ball steep light the best low cost, unfenced driven solutions, PF value greater than 0. 9, THD is less than 20%, the ripple is less than 15%, other properties with SSL5021B.

NXP power and lighting plan product line manager Ryan Zahn said: 'the NXP non dimming LED drive SSL5101 and dimming LED drive SSL5301 has the global professional LED lighting market has proved its excellent performance, today we are again on the basis of its successful development TSOP6 encapsulation of low-cost SSL5021B entry-level products / 5031 b and SSL5231/5236/5237, these products will greatly enhance our mid-range LED general lighting in China in 2015 the competitiveness of the market. '

he said, adding that SSL5021B and SSL5031B a major selling point is to support the costs are lower than those of MOSFET transistor as switch tube, however, if you use triode, had better not more than 9 watts output power.
