Ballast Control Eases Industrial HID Lighting Apps

The IRS2573DS high-intensity discharge (HID) electronic ballast control IC promises to simplify low-, medium-, and high-power general-purpose industrial HID applications. The 600V IC combines a high-side, dual-mode buck controller together with a full-bridge driver. It employs novel buck circuitry that enables continuous-conduction mode control during lamp warm-up and critical-conduction mode during steady state running. The full-bridge driver includes all high- and low-side gate driver outputs as well as integrated bootstrap MOSFETs for the high-side supply voltages. Additionally, the IRS2573DS offers comprehensive fault detection and fault timer circuitry to detect open circuit, short circuit, failure to ignite, failure to warm-up, and lamp end-of-life fault conditions. Available in a 28-pin SO28-WB package, pricing for the IRS2573DS begins at $2.50 each/10,000. For more information, contact Sian Cummins INTERNATIONAL RECTIFIER CORP., El Segundo, CA.
