The LED driver based on the technology of GreenChip

Shanghai, China, October 29, 2012 - — Grace wisdom pu semiconductor ( NXP半导体N。 V。 ) ( Nasdaq code NXPI) Today issued SSL2129A - — A compact depth is adjustable for 4 to 25 W leds light efficient GreenChip ™ controller IC. SSL2129A provide per watt compatibility degree as the first-class dimming performance measurement basis, for single stage mainstream type LED driver applications. This kind of convenient method still can keep applying compact ( GU10/PAR16) And high cost performance, the high power factor ( PF) Greater than zero. 9. This device is designed for use with external MOSFET, can be configured to buck, The isolation) Or flyback ( Isolation) Topology for 100 to 120 v and 230 v mains supply voltage. Grace wisdom pu will be in Hong Kong international lighting fair ( Booth number 5 b - C12) Show the latest SSL drive green chip series.

grace wisdom pu semiconductor lighting solutions of global product marketing manager Mr Richard Langezaal said 'our latest GreenChip LED controller IC set a new benchmark for dimmer compatibility degree. 'Per watt compatible degree' in test and measurement, we considered under the condition of the low level of input power adjustable light LED the importance of performance, and many other factors. SSL2129A can offer excellent on extremely compact size adjustment made in optical performance, high efficiency and convenience, thus will help to significantly reduce the cost of modified type adjustable light LED lights. '

assessment per watt compatible degree

the world has now sold more than 600 kinds of dimmers, and almost every product initially for incandescent lamp design. For lighting products manufacturers, using a variety of dimmer design reliable performance and stable adjustable light leds is still a very big challenge. At the same time, because the LED efficiency ( Number of lumens per watt) Improved steadily, the decrease of input power needed for the improvement of LED lights, it's brought additional problems at present, used for commercial purposes of LED lights need to 7 W instead of 40 W incandescent lamp, to 8. 7 W instead of 60 W incandescent lamp. But is under 10 W, maintain the dimmer compatibility degree becomes particularly difficult.

in order to solve this problem, think pu worked out the 'per watt compatible degree' grading method, will absorb the mains input power and the stability ( Avoid flashing, shimmering and flash visual distractions such as ability) And control ( Users can control and reduce the degree of light output, including dimming range lighting levels, control room and step) Compatible with the degree of indexes such as scope into account. SSL2129A based on the parameter showed excellent dimmer compatibility. Grace wisdom pu will be published later provide assessment dimmers compatible degrees per watt of the white paper.

the key features of SSL2129A, which can reduce the cost of eBOM compact single-stage LED driver solution

• benchmark dimmers compatible degrees per watt SSL driver IC,

• pure controller for the segregation and isolation type two kinds of topological

, specially designed for improved 4 to 25 W lamp,

(high efficiency and high power factor, PF >0. 9)

, easy to use, easy to manufacture listed time

SSL2129A compact depth adjustable light controller IC used in LED lighting, is now mass production, can get the sample immediately.
