PI released the latest reference design based on single stage LinkSwitch-PH LED driver IC series devices - DER-278

Recently, off-line LED high voltage driver Power Integrations lighting company (POWI) announced a new reference to the company's design of single stage LinkSwitch-PH LED drive IC series devices based on (DER-278), eliminating the electrolytic capacitor and the optical isolator is not reliable, suitable for the high reliability requirements of industrial, commercial and outdoor solid state lighting (SSL) application. LinkSwitch Power Integrations unique products adhering to the efficient and accurate single primary side control technology, can also save the commonly used traditional electrolytic capacitor isolation flyback design and reliable optocoupler. When designers use LinkSwitch-PH IC to design SSL products, the working life of the drive can exceed 35000 hours required by the ENERGY STAR SLL (V1.1) specification. Power Integrations vice president of marketing Doug Bailey said: "the municipal authorities, retailers, industrial users and other enterprises now find early rational investment in LED lighting should consider not only the LED lamp to save energy, but also lower during the whole service life and maintenance costs. However, the degree of realization of this advantage depends mainly on the choice of drive technology. PI single stage LinkSwitch-PH series device can eliminate the weak link in typical LED driver. If you use the LinkSwitch-PH driver IC LED designer and ceramic capacitors with high reliability, the lighting system can design efficient, safe and cost-effective, its working life longer than solid state lighting lighting using consumer grade drives, and can save expensive maintenance fees. "LinkSwitch-PH IC enables the designer to optimize system efficiency, meet or exceed all standards including energy star and EN61000-3-2. The sample can be supplied without halogen and eSIPTM-7C package in accordance with the requirements of ROHS, and the price of the 10000 order quantity is between $1.18 and $1.71 per piece.
