control ICs
International Rectifier has introduced the IRS2530D and IRS2158D 600V control ICs for energy-efficient dimming fluorescent lighting ballast applications.
The IRS2530D Dim8 is a linear dimming ballast control IC with half-bridge driver in a compact 8-pin form factor.
It replaces inefficient incandescent bulbs in multi-level and three-way compact fluorescent lighting (CFL) applications.
Requiring several small external components, the IRS2530D significantly simplifies and shrinks circuit design, and delivers a dimming system performance of up to 10 per cent for compact fluorescent lamps as well as linear ballasts.
The IRS2158D 16-pin fluorescent dimming ballast control IC with half-bridge driver is designed for applications requiring dimming performance below 10 per cent.
Comprehensive protection features, such as protection from failure of a lamp to strike, filament failures and end-of-life protection are offered, making the device well-suited for thin lamps including the T5 lamp.
