IRS2530D(S)

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.

† This IC contains a zener clamp structure between the chip VCC and COM which has a nominal breakdown voltage of 15.6V. This supply pin should not be driven by a DC, low impedance power source greater than the V_CLAMP specified in the Electrical Characteristics section.

†† This IC contains a zener clamp structure between the chip VCO  and COM which has a nominal breakdown voltage of 7.25V. This pin should not be driven by a DC, low impedance  ower source greater than the V_VCOMAX specified in the Electrical Characteristics section.

This IC IRS2530D(S) takes full advantage of IR's patented ballast and high-voltage technologies to realize a simple,  ighperformance dimming ballast solution. 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 the AC lamp current feedback have been coupled together allowing a single pin to be used for dimming. Combining these high-voltage control algorithms together with a simple dimming method in a single 8-pin IC results in a large reduction in component count, an increase in manufacturability and reliability, a reduced design cycle time, while maintaining high dimming ballast system performance
