Dimming Ballast Control Ic -

Description: The IR2159 IR21591 are complete dimming ballast controllers and 600V half-bridge drivers all in one IC. The architecture includes phase control for trans- former-less lamp power sensing and regulation which minimizes changes needed to adapt non-dimming ballasts for dimming. Externally programmable features such as preheat time and current, ignition-to-dim time, and a complete dimming Interface with minimum and maximum settings provide a high degree of flexibility for the ballast design engineer. Protection from failure of a lamp to strike, filament failures, thermal overload, or lamp failure during normal operation, as well as an Automatic restart function, have been included in the design. The heart of this control IC is a voltage- controlled Oscillator with externally programmable minimum frequency. The IR2159 IR21591 are available in both 16 pin DIP and 16 pin narrow body SOIC packages. By International Rectifier Corp.
