LED driver IC suppliers compete to publish highly integrated dimming solutions. Faced with the increasing cost challenges of dimmable LED lighting systems, chip vendors are working hard to develop highly integrated dimming solutions that support hardware and software functions such as temperature compensation, drivers, and programmable registers to assist LEDs. Lighting system operators reduce the overall bill of materials (BOM) cost of dimming products.
Girish Ramesh, senior product marketing manager at Atmel, said that in view of the rising demand for dimming driver ICs for LED lighting applications such as general lighting, residential lighting, commercial lighting, architectural lighting and scene lighting, the company has launched a few days ago. Combined with high-integration schemes such as temperature compensation, driver, programmable register and other hardware and software functions, it is estimated that compared with competitors' products, LED lighting system operators can save BOM according to the rated power of different fixtures. The cost is 0.5 to 1 US dollar.
Compared with the price of non-dimming LED driver IC has dropped below 0.4 US dollars, the current price of dimmable LED driver IC is still higher than 1 US dollar. However, under the aggressive cost reduction of various LED driver IC manufacturers, the unit price of dimmable LED driver ICs in 2013 is expected to drop to less than $1.
It is understood that Atmel's latest dimmable LED driver IC solution will eliminate the temperature-compensated microcontroller (MCU) and the power diode function that can implement the driver function through the built-in temperature compensation and driver software. , inductors and output capacitor components. In addition, the programmable scratchpad makes it easy to control and monitor fault detection systems.
Not only Atmel, but also Texas Instruments has introduced a highly integrated dimmable LED driver IC solution that reduces component count and product size for off-line AC-to-DC (LED) illumination and cartridges. Down Light and E14, GU10, A19, PAR20/30/38, MR16 and AR111 bulbs. The company's simple hysteresis input current control scheme eliminates complex loop compensation and is highly compatible with transformers; and integrates an active low-side input rectifier (Rectifier) ​​to increase efficiency while simplifying design and reducing BOM cost.
