Description

Description: The IR21593S are complete dimming ballast controllers and 600V half-bridge drivers all in one IC. The architecture includes phase control for transformer- 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 of the IR21593S 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 voltagecontrolled oscillator with externally programmable minimum frequency. The IR21593S are available in both 16 pin DIP and 16 pin narrow body SOIC packages.
