The five big market demand trend current drive power LED lighting can be summed up as: high efficiency, high reliability, dimming and non application compatibility, light widely more and more small volume, no optocoupler.
Paul Zhu, vice president of sales of iWatt company
To meet the application market of LED lighting drive power is more and more high requirements, LED drive suppliers must have adequate technical reserves, in order to gain a foothold in this market. The American iWatt company is one of the leading suppliers of this market, patented mature PSR (primary control) control technology, this technology makes it possible to develop without coupling and not suitable for application in the design of the LED driver in high temperature environment, thus greatly improves the reliability of the LED driver.
In addition, application of iWatt a few years ago began to light, and the development of the 3610 and 3620 series LED control IC. When the power supply designer with iWatt plan development, they can easily solve the relationship between fever and volume, because the LED driver of the volume of products will become more and more small, resulting in power density become larger. Currently iWatt offers a series of LED driver IC, suitable for the development of LED lighting from 3W to 30W, the basic coverage of the current mainstream LED lighting power range. There are cost-effective for small power 3W iW1696 and iW1678, there will be a BJT transistor integrated with the Gao Jicheng of iW1810, with different MOSFET flexibly for different power levels of iW3620, and the dimmer is the best compatibility with iW3610/3612 series IC, see the following table. IWatt LED driver for the development of small size, high power density, high efficiency and low ripple output of high-quality LED lighting. For iWatt's future LED drive product development roadmap, iWatt Sales Vice President Paul Zhu said: "the overall guiding ideology of our development of LED driver IC is to improve the distribution of products, application of simplified designers, and maintain price competitiveness.
