Power Integrations new products can achieve TRIAC dimming function

Business information report, Power Integrations (Nasdaq:POWI) the energy-saving power conversion high voltage integrated circuit leader announced that the new LED driver IC two series, whose products are characterized by bidirectional thyristor dimmer, single stage power factor correction has been. Target applications - solid state lighting (SSL). (LinkSwitch-PH most suitable for the isolated system) and LinkSwitch-PL (the most suitable for the non isolation system) can realize one-way flashing TRIAC dimming, and similar incandescent lighting user experience. LinkSwitch-PH and LinkSwitch-PL series features the integration of single stage power factor correction (PFC), can make SSL lighting efficiency reached PF > 0.9. The LinkSwitch-PH device also incorporates the primary side control technology, eliminating the need for the use of optical couplers and support assemblies in conventional isolated flyback designs. Non isolated LinkSwitch-PL design can further reduce the number of components, enhance the reliability and reduce the cost of the bill of materials (BOM). The two series is a single chip IC, which is the controller and the MOSFET integrated into a silicon chip, through the number of components is reduced to the minimum, and eliminates the parasitic capacitance between the controller and the power MOSFET, which simplifies the PCB layout. The new LinkSwitch products for simple flyback (Flyback) design of high efficiency were optimized in the input voltage up to 305 VAC, and can be developed for various residential and commercial lighting applications global single voltage and general input products. Maker in the temperature range and the driving current in the wire operation, LED hours of work can be expected to be more than 50000 hours. The weakest link in the LED lighting system is the drive circuit, which will bear the burden of optical coupler and electrolytic capacitor. Power Integrations precision primary side control technology, the key technology in LinkSwitch products use, can save the optical coupler, and the new LinkSwitch LED drive IC series products completely without the use of large electrolytic capacitor. Designers of the LinkSwitch-PL and LinkSwitch-PH products for SSL can expect the operating life of the drive to be in line with its precise control of the life of the LED array. Power Integrations lighting business development manager (BillWeiss) pointed out: "the two new series of products is the most suitable to replace general lighting, and the space limitations of the LED drive. LinkSwitch-PH series is the most suitable for isolation design and rated output power of 50W, the effect is more obvious on the external LED ballast, often used in downward lighting, building lighting, signs and outdoor lighting. These two devices can reduce the number and size of the system BOM, thereby improving system reliability. This IC allows designers to optimize system efficiency and meet or exceed all statutory standards, such as energy star and EN61000-3-2 standards. "LinkSwitch-PH samples are currently available in eSIP-7C package without halogen, conforming to ROHS standard, each priced at $1.18 to $1.71, each order quantity is 10000. LinkSwitch-PL IC will launch in August 2010 a small sample of SO-8 and eDIP -12 package.
