Fluorescent Ballasts Slash Component Counts

The IRS2530D and IRS2158D 600V controllers for dimming fluorescent lighting ballast applications promise to boost efficiency while trimming down component counts. The IRS2530D DIM8, a linear dimming ballast control IC, integrates a half-bridge driver in an eight-pin form factor. Requiring only several small external components, the device simplifies and shrinks circuit designs and delivers a dimming system performance up to 10% for compact fluorescent lamps as well as linear ballasts. The IRS2158D 16-pin fluorescent dimming ballast controller with half-bridge driver targets applications requiring dimming performance below 10%. Protection features such as protection from failure of a lamp to strike, filament failures, and end-of-life protection are on chip, making the device suitable for thin lamps including T5. Prices for the IRS2530D and IRS2158D are $1.09 and $1.29 each/10,000. INTERNATIONAL RECTIFIER, El Segundo, CA. (310) 252-7726.
