          70W HID燈IRPLHID2參考設計

          The IRPLHID2 reference design kit consists of a complete ballast solution for a 70W HID lamp. The design contains an EMI filter, low voltage power supply, active power factor correction and a ballast control circuit using the IRS2573D. This demo board is intended to help with the evaluation of the IRS2573D HID ballast control IC, demonstrate PCB layout techniques and serve as an aid in the development of production ballasts using the IRS2573D.

          IRPLHID2參考設計主要特性:

          Drives 1 x 70W HID lamp

          Input voltage range: 185-265 VAC

          High Power Factor / Low Total Harmonic Distortion

          Controlled ignition

          Low frequency square wave operation

          Lamp power and current control

          Open circuit and no-lamp protection

          Short circuit and lamp failure to warm-up protection

          Lamp end-of-life shutdown

          IRS2573DSPbF HID Ballast Control IC
