Input voltage185-265 V
Switching frequency160-240 kHz

Description

The IRS2573D is a fully-integrated, fully-protected 600V HID control IC designed to drive all types of HID lamps.Internal circuitry provides control for ignition, warm-up, running and fault operating modes. The IRS2573D features include ignition timing control, constant lamp power control, programmable full-bridge running frequency,programmable over and under-voltage protection and programmable over-current protection. Advanced protection features such as failure of a lamp to ignite, open load, short-circuit and a programmable fault counterhave also been included in the design.
