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
