IR Introduces Industry's First PFC and Ballast Control IC Integrated in an 8-Pin SO-8 Package for Energy Efficient Lighting Applications

International Rectifier IRS2580DS

International Rectifier (IR) introduced the industry’s first IC to integrate power factor correction (PFC) and ballast control in a single compact 8-pin SO-8 package. The new IRS2580DS Combo8 IC simplifies design and reduces overall component count to speed up design in energy efficient lighting applications.

The IRS2580DS includes a boost converter control circuit operating in critical-conduction free-running frequency mode to provide power factor correction with ultra-low THD. The new IC also includes a 600 V half-bridge control circuit working at 50 percent duty-cycle and variable frequency for driving the resonant mode lamp output circuit.

Complete fault protection circuitry is also included for protection against such conditions as mains interrupt or brown-out, lamp non-strike, lamp filament failure and end-of-life. The IRS2580DS requires only two primary control pins to perform all of the necessary ballast functions. These functions include an analog voltage-to-frequency input pin for programming the different operating frequencies for preheating, igniting and running the lamp, and a PWM output pin for controlling the on and off times during each switching cycle of the PFC boost converter.
