Description: The IR21592/IR21593 are complete dimming ballast controllers and 600V Packages
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 ofthis control IC is a voltage-
controlled oscillator with externally programmable minimum frequency. The IR21592/
IR21593 are available in both 16 pin DIP and 16 pin narrow body SOIC packages.

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.

Note 1: This IC contains a zener clamp structure between the chip Vcc and COM which has a nominal breakdown
voltage of 15.6V (VCLAMp). Please note that this supply pin should not be driven by a DC, low impedance
power source greater than the diode clamp voltage (VCLAMP) as specified in the Electrical Characteristics
section.
