International Rectifier’s IRS2573DS is a high-intensity discharge (HID) electronic ballast control IC for low-, medium- and high-power general purpose HID applications including retail store spotlights, general outdoor lighting applications and outdoor street lighting. The 600 V IC combines a high-side, dual-mode buck controller together with a full-bridge driver. Its novel buck circuitry 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. The device incorporates a state machine for controlling the lamp during various operating modes including ignition, warm-up, running and fault mode, and features a multiplier circuit to accurately measure and control lamp power.
