It uses just 13 components and has integral protection features including open loop, short-circuit and over temperature. It features PI’s patented frequency jittering technology and it supports universal inputs from 90 to 235VAC. Using more components multiple topologies are supported including low-side buck, buck boost, flyback and boost.
Reference Design Kits include a working power supply, sample devices, unpopulated pcb, data sheet, comprehensive engineering report, PI Expert design software and other related documentation.
Using PI Expert designers can create a schematic and layout to produce a Bill of Materials. This can be exported to check part availability at PI’s high service distribution partners. The aim is to reduce design time for engineers.
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.
