Wurth Electronics Midcom Inc. and Infineon Technologies have teamed up to create the ICL8001G LED driver application for 40/60/100W incandescent bulb replacement for US and European markets. The design provides unmatched power quality, with a power factor exceeding 95%.
Featured on the ICL8001G design is a custom Wurth Electronics Midcom flyback transformer (US: 750311798; EUR: 750815141) and WE-TFC series (744862120) power line common mode choke. The transformer provides high energy storage in a compact design with low copper losses. The design offers reinforced insulation to IEC61558-2-17 and has an operating temperature from -40°C to +125°C. The common mode chokes feature high suppression of symmetric interferences, even at low frequency ranges. Regardless of the small size, the choke provides low copper losses. Operating temperature range is -55°C to +105°C.
The LED lighting design is a quasi-resonant controller that creates an ideal solution for dimmable retrofit LED light bulbs. The ICL8001G offers efficiencies up to 90% with superb light quality. The solution uses primary side control which results in a fully isolated design without requiring additional components. With the reduced component count, this design results in approximately 30% BOM savings. Multiple safety functions also ensure a full system protection in failure situations.
