Power Integrations newly launched LinkSwitch-PH and LinkSwitch-PL series

Single stage power factor correction and accurate constant current output control can significantly reduce the number of components of an off-line LED driver

California San Jose, June 9, 2010 - for high voltage integrated circuit industry high efficient power conversion of the leader of the Power Integrations company (NASDAQ: POWI) today announced the launch of two for solid state lighting (SSL), the application of single stage power factor correction support TRIAC dimming LED driver IC. They are LinkSwitch-PH (suitable for the design of isolated power supply (LinkSwitch-PL) and suitable for the design of non isolated power supply), both of which can be achieved without blinking monolithic TRIAC dimming, achieve lighting effects similar to incandescent lamp.

LinkSwitch-PH and LinkSwitch-PL series of products are integrated with the single-stage power factor correction (PFC), which can make the power factor of SSL lamp can reach more than 0.9. The primary side control technology is used in the LinkSwitch-PH device, so it can be omitted from the traditional flyback design commonly used optocoupler and many auxiliary components. Non isolated LinkSwitch-PL design can further reduce the number of components, not only can improve the reliability of the system, but also can reduce the bill of material costs (BOM). The two devices are designed with a single chip. The controller and the MOSFET are integrated on a single chip, so that the number of components can be reduced and the parasitic elements between the controller and the power MOSFET can be omitted, so the PCB layout can be greatly simplified. These new LinkSwitch products can not only simplify the design of flyback power supply, but also can improve its efficiency, and can work in input voltage up to 305 VAC under single voltage products so that they can be used in various kinds of global development suitable for residential and commercial lighting applications and general input products.

Maker in the specified temperature and driving current range, the service life of the LED is expected to reach more than 50000 hours. The weakest link in the LED lighting system is the drive circuit, because it is often involved in unreliable optocoupler and parasitic capacitance. LinkSwitch products in the use of the Power Integrations unique precision primary side control technology can be omitted optocoupler. Moreover, the new LinkSwitch LED driver IC family does not require the use of large capacity parasitic capacitors. Designers in the use of LinkSwitch-PL and LinkSwitch-PH design SSL products, it can be predicted that the working life of the driver and the precise control of the LED array.

Power Integrations lighting business development manager Bill Weiss said: "these two new products are very suitable for the design of replacement lamps in the limited space of LED driver. LinkSwitch-PH series of products designed for isolated power supply, its rated output power up to 50 watts, so it is very suitable for external LED ballasts commonly used design downlight, architectural lighting, outdoor lighting and signage. These two devices can reduce the number and size of BOM devices in the power system, thereby enhancing the reliability of the system. These IC will enable designers to improve the efficiency of the system, to meet or even exceed all the regulatory standards, including energy star and EN61000-3-2. "

LinkSwitch-PH device can now no halogen, samples with eSIPa-7C package delivery requirements of ROHS, between 10000 pieces of quantity price between $1.18 and $1.71 per piece. LinkSwitch-PL IC will be available in August 2010 and will be available in compact SO-8 and eDIP -12 packages.
