The same integrated high voltage MOSFET product family for non-dimming SSL21081 (A) / 83 (A), with high integration, fewer external components requires only 14, so the overall cost is lower, due to the integrated MOSFET, efficiency are more than 95%. However, this scenario PF can only do greater than 0.7. “SSL21081 (A) / 83 (A) can achieve 5% current accuracy control of output and 95% efficiency, fully protective function and built-in flexible and reliable features ensure the lowest cost of system components by the user of the Asia welcomes, which will be the flagship product in the next two years. ” He explained, Not all IC companies can put high-voltage MOSFET integrated into the controller, NXP high-voltage insulated SOI process can achieve good heat dissipation, which integrated high voltage MOSFET to achieve high efficiency lighting, integrated 750V for some MOSFET, NXP integrate only to 600V MOSFETs, Wang Yongbin explain, from a look at the current and present, the integrated 600VMOSFET is enough, an increase is a waste and cost.”
And for the next two years, it will become the mainstream of the high-power LED tube china lighting market. NXP severely launched the SSL4120, which is an integrated power factor correction (PFC) Green Chip. Half-bridge resonant controller can support up to 400W of high power LED tube china application, which currently in volume production, the sample is also forth coming. The SSL4120 completely support mains applications, to support the efficient start directly from the rectified universal mains voltage range of 90-305 volts. In addition, it supports less than 10% of the low total harmonic distortion (THD), higher than the 0.97 high power factor (PF) and the typical PFC 380 kHz frequency, to meet and exceed the traditional requirements of high-power LED lighting applications. SSL4120 can be widely used in high-power LED Tubes applications, such as office lighting, shopping malls lighting, high-bay and low bay lighting, parking lot lighting, square lighting and street lighting.
Finally, when talked about some lighting manufacturers who are making their own vertical integration of R & D-driven IC / components trend, Wang Yongbin think that this is just a temporary phenomenon, and will not become mainstream. Lighting company that need to do the electronic part is still difficult, still specialization, so in the future, it will drive apart and be independent. “His personal view.
