New from International Rectifier are the IRS2530D and IRS2158D 600 V control ICs for energy-efficient dimming fluorescent lighting ballast applications.
The IRS2530D DIM8 is a linear dimming ballast control IC with a half-bridge driver in a compact 8-pin form factor. The new device provides a competitive solution to replace inefficient incandescent bulbs in multilevel and three-way compact fluorescent lighting (CFL) applications. Requiring only several small external components, the IC simplifies and shrinks circuit design and delivers a dimming system performance of up to 10% for CFLs as well as linear ballasts.
The IRS2530D DIM8 features IR’s patented ballast and high-voltage technologies. A single high-voltage pin senses the half-bridge current and voltage to perform necessary ballast protection functions. The DC dim input voltage reference and AC lamp current feedback are combined, allowing a single pin to be used for dimming. The device also features an internal non-ZVS protection and internal crest factor protection to prevent lamp failure from damaging the ballast.
The IRS2158D 16-pin fluorescent dimming ballast control IC with half-bridge driver is designed for 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 offered, making the device well suited for thin lamps including the increasingly popular T5 lamp.
The IRS2158D is a fully integrated, fully protected 600 V ballast control IC designed to drive a wide variety of fluorescent lamps. The device’s features include programmable half-bridge over-current protection, programmable pre-heat and run frequencies, programmable preheat time and dead-time, closed-loop half-bridge ignition current regulation, programmable end-of-life protection, brownout protection and low input offset operational amplifier for dimming, current or power control. In addition, it features an end-of-life window comparator pin and internal 60-event current sense up/down fault counter to accommodate T5 lamp and multilamp ballasts.
