LED Driver ICs work with non-dimmable GU10 bulbs.

Press Release Summary:

LYTSwitch™-0 ICs for non-isolated, non-dimmable bulbs in space-constrained applications feature efficiencies of more than 90%. Units also typically deliver constant current of more than ±5% regulation. With power factor greater than 0.8 at 115 Vac and 0.55 at 230 Vac, ICs comply with ENERGYSTAR™ V1 draft 3 standards for North America and Ecodesign Directive Lot 19 part 2 for Europe. 

Original Press Release:

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

SAN JOSE, CALIF. – Power Integrations (Nasdaq: POWI), the leader in high-efficiency, high-reliability LED-driver ICs, today introduced its LYTSwitch™-0ICs, a new series of devices within the LYTSwitch family, offering a unique combination of simplicity, reliability and efficiency. LYTSwitch-0 ICs are ideal for cost-sensitive, non-isolated, non-dimmable GU10 bulbs and other space-constrained bulb applications.

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 driver - see http://www.powerint.com/sites/default/files/PDFFiles/rdr355.pdf. LYTSwitch-0IC samples in SO-8 and DIP packagesare available now, priced at $0.29 each in 10,000-piece quantities. Datasheet and introduction video are available on the Power Integrations website at http://www.powerint.com/en/products/lytswitch-family/lytswitch-0.
