Power Integrations Launches LYTSwitch-0 Family of Highly Integrated LED-Driver ICs for Low-Power LED Bulbs

LYTSwitch-0 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 VAC and 0.55 at 230 VAC, meeting ENERGYSTAR™ V1 draft 3 consumer lighting standards for North America and Ecodesign Directive Lot 19 part 2 for Europe.

Comments Andrew Smith, product marketing manager for Power Integrations: “RDR-355 describes a GU10 LED driver using the LYTSwitch-0 IC and just 13 components. The device’s small size and high efficiency eliminate the need for heatsinking or potting of the LED driver, reducing manufacturing cost.”

Key applications include low-cost LED light bulbs such as GU10 and candelabra styles. RDR-355 describes a 6 W non-dimmable LED, samples in SO-8 and DIP packages are available now, priced at $0.29 each in 10,000-piece quantities.
