Drive IC plant to promote the integration of high integration program aimed at dimmable LED lighting

Light emitting diode (LED) driver IC vendors are actively engaged in dimmable LED lighting market program. Unless the dimming LED lighting system, light adjustable LED lighting system cost challenge is also increasing, so the business is trying to support the development of wafer temperature compensation, driver, programmable register (Register) and other hardware and software function of highly integrated dimming scheme, LED lighting system to assist the industry as a whole bill of material transfer light products (BOM) to reduce the cost.

Dimming scheme integrating LED driver IC 'crazy factory price

Art Mel (AtmEL) senior product marketing manager Girish Ramesh said, in view of general lighting, residential lighting, commercial lighting, architectural lighting and scene lighting LED lighting applications for dimming driver IC bullish demand, the company has launched a high degree of integration scheme combined with temperature compensation, driver, programmable register the software and hardware function on the day before, estimate and competitor products compared, according to the different fixture (Fixture) rated for LED lighting system operators to save 0.5 BOM $1 cost?.

Compared to non dimming LED driver IC unit price has fallen below $0.4, at this stage adjustable light LED driver IC price is still higher than $1. However, in the various LED driven IC manufacturers actively cut costs, in 2013 adjustable light LED drive IC unit price is expected to fall below $1.

It is understood that Mel's new Aite dimmable LED driver IC high integration scheme through the built-in temperature compensation and driver software, will save the micro controller is responsible for temperature compensation (MCU), and can realize the power diode, inductor and output capacitor element driver function. In addition, programmable registers can easily control and monitor the fault detection system.

Not only is Mel Aite (TI) recently, TI also launched a highly integrated dimmable LED driver IC scheme can reduce the number of components and product size, used in off-line AC to DC (AC-DC) LED (Down Light), the lighting lamp and E14, GU10, A19, PAR20/30/38, MR16 and AR111 bulbs. The company by the current control scheme of simplified hysteresis loop compensation input, save complex, and highly compatible with the transformer; and integrating active low side input rectifier (Low-side) (Rectifier) to improve the efficiency, and simplify the design and reduce the cost of BOM.

Benefit from the LED driver IC manufacturers push high integration program, LED dimming drive IC and non dimming program spreads have been significantly reduced, is expected to drive LED dimming driver IC in 2013 accounted for a substantial rise in the market.

Dimming with non dimming scheme to narrow the LED dimming drive IC demand growth

In addition to improve the integration of givers, LED lighting driver IC manufacturers also use simplified printed circuit board (PCB) design to achieve the purpose of reducing the price. At present, light adjustable LED lighting driver IC price has fallen sharply, and non dimming driving scheme spread rapidly reduced to below $0.3, is expected to attract LED lighting and lighting manufacturers use a large number of.
