Description
Description: The IR2159/IR21591 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 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 IR2159/ IR21591 are available in both 16 pin DIP and 16 pin narrow body SOIC packages.

Enough current should be supplied into the VCC lead to keep the internal 15.6V zener clamp diode on this lead regulating its voltage, VCLAMP. The MAX lead is a voltage-controlled current source. For optimum dim interface current mirror performance, this current should be kept between 0 and 750µA.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
