Integrated LED-Driver ICs For Low-Power LED Bulbs

Power Integrations introduced its LYTSwitch(tm)-0 ICs, a new series of devices within the LYTSwitch family, offering a unique combination of simplicity, reliability and efficiency.

Aug. 28, 2013

The LYTSwitch™-0 ICs, a new series of devices within the LYTSwitch family from Power Integrations, are suited 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.

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-0 IC samples in SO-8 and DIP packages are available now, priced at $0.29 each in 10,000-piece quantities.
