Industry’s First PFC and Ballast Control IC Integrated in an 8-Pin SO-8 Package The IRS2580DS is the industry’s first IC to integrated 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. PRESS RELEASE DATA SHEET HI-RES GRAPHIC LIGHTING HOME PAGE Features Advantages • • • • • • • • • The IRS2580D 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 600V half-bridge control circuit working at 50 percent duty-cycle and variable frequency for driving the resonant mode lamp output circuit. • Unlike alternative approaches, the IRS2580DS Combo8 IC offers excellent PFC performance, a high degree of accuracy and ultra-low THD across a wide line and load range in a single 8-pin package. • Because two of the eight pins are the primary control pins for the complete ballast, it provides a simple solution with reduced component count that significantly speeds up design time. • Complete fault protection circuitry is also included for protection against such conditions as mains interrupt or brown-out, lamp nonstrike, lamp filament failure and end-of-life. • The IRS2580DS requires only two primary control pins to perform all of the necessary ballast functions. • • • • • • • • • • • • • PFC, ballast control and half-bridge driver in one IC Critical-conduction mode boost-type PFC Internal VBUS sensing and regulation Internal PFC loop compensation Programmable PFC over-current Ignition voltage regulation (current or voltage control) Half-bridge non-ZVS protection Half-bridge over-current protection using low-side MOSFET RDS(on) Programmable preheat time Programmable preheat frequency Programmable ignition ramp time Programmable run frequency Voltage-controlled oscillator (VCO) analog input Latched EOL window comparator on VCC Internal EOL fault timer Fixed dead-time (1.7usec typ) DC bus under voltage reset Micro-power start-up current Under-voltage lockout mode Small 8-pin SOIC package Lead free May 2011
