The IRS2530D DIM8TM is a unique linear dimming ballast control chip with a compact 8-pin half-bridge driver. The new device offers a multi-stage and three-way compact fluorescent (CFL) application solution. The IRS2530D requires only a few small external components to simplify and reduce the circuit design while achieving up to 10% dimming system performance for compact fluorescent and linear ballasts.
The IRS2158D 16-Pin Fluorescent Dimming Ballast Control IC with half-bridge driver is suitable for applications requiring less than 10% dimming performance. This component has comprehensive protection features (such as preventing the bulb from igniting, filament failure and lamp scrapping protection), making it ideal for thin lamps including T5 bulbs. The device expands its portfolio of energy-efficient products, saving up to 30% in energy compared to non-dimming lighting. Designers can use different control methods to create new dimming product lines. The new control ICs are highly integrated and protected, enabling the small size, functionality and performance required while reducing component count and simplifying design.
The IRS2158D is a fully integrated, fully protected 600V ballast control IC for driving a wide range of fluorescent lamps. The device's features include programmable half-bridge overcurrent protection, programmable warm-up and operating frequency, programmable warm-up time and dead time, closed-loop half-bridge ignition current regulation, programmable end-of-life protection, undervoltage protection, and low dimming Input compensation op amp and current or power control. In addition, the new device features a scrap range comparator, pin and internal 60 event current sense up/down fault counters to meet the requirements of T5 bulbs and multi-bulb ballasts.
