Power Integrations introduced LYTSwitch-0, a new series of LED drivers offering a combination of simplicity, reliability and efficiency ideal for cost-sensitive, non-isolated, non-dimmable GU10 bulbs and other space-constrained bulb applications.
The devices feature efficiencies of more than 90% and deliver constant current with better than ±5% regulation in typical applications. Power factor is greater than 0,8 at 115 V a.c. and 0,55 at 230 V a.c., meeting ENERGY STAR V1 draft 3 consumer lighting standards for North America and Ecodesign Directive Lot 19 part 2 for Europe.
The drivers are available in SO-8 and DIP packages. Their small size and high efficiency eliminate the need for heatsinking or potting of the LED driver. A reference design note is available describing a GU10 LED driver using the LYTSwitch-0 and just 13 components.
