Recently, PI company introduced a new LED driver named ICLYTSwitch-0 series, the device is set simplicity, reliability and efficiency in one, ideal for cost-sensitive, non-isolated, non-dimmable GU10 bulbs and other space constrained bulb applications. Define any semiconductor company a new product, we must conduct a detailed target market research, then this new series of LED driver IC is behind what technology trend here.PI's product marketing manager AndrewSmith said, LED lights spread process depends on its rate of decline in prices, while 40% of the cost of LED lights spent in drive control circuit, including LED driver IC control circuit including cost reduction is essential .According to IMSReserch company in April 2012 report showed, LED lamp prices tend to be $ 30 in 2009, all the way down, around 2017 will exceed $ 5 mark. Corresponding to this is that the cost will drive control circuit 2013 to 2015 is expected to reduce between 36%.LED light in accordance with future market requirements for the driver circuit, AndrewSmith analyzed LED driver power supply technology trends. He believes, LED drive power will be more often isolated to non-isolated transition, the total number of components must be reduced as much as possible, while the constant current drive power efficiency and quality have been improved, but the premise is to meet low cost.According to Andrew Smith's introduction, the company launched PI LYTSwitch-0 device efficiency can reach 90% in typical applications to better than + / -5% regulation accuracy to provide constant current output. Under the power factor greater than 0.8 at 115VAC, 230VAC achieved under the 0.55, which can meet ENERGYSTAR? V1 third draft of the North American consumer lighting standards, as well as the European Eco-design Directive Lot19 Part 2 standard.In order to better demonstrate the new devices on the driver circuit change, PI company also introduced a design kit RDK-355, it is a use LYTSwitch-0IC and only 13 elements designed by GU10LED drive circuit, this 6W non-quenched light LED driver circuit applications include candle lights and other low-cost GU10 LED bulbs.
