IR IRPLHID2 70W HID灯镇流器参考设计

IR公司的70W HID(氙气灯)镇流器参考设计IRPLHID2采用IRS2573D器件,输入电压185V-265V,可驱动1 x 70W HID灯,具有高功率因素/低总谐波失真,可控制起辉,低频方波工作,灯电流和功率可控制,开路和无灯保护.而IRS2573D是全集成全保护的600V HID控制器,能驱动所有类型的HID灯,内部电路提供了起辉,加热,运行和故障保护模式.本文介绍了IRS2573D主要特性,框图,应用框图以及采用IRS2573D的70W HID灯镇流器IRPLHID2参考设计主要指标,参考设计框图和电路图,以及材料清单和PCB布局图.

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 counter

have also been included in the design.

IRS2573D主要特性:

• Buck, full-bridge and lamp control in one IC

• Continuous/critical-conduction mode buck control

• 600V high and low-side full-bridge driver

• 600V high-side buck Driver

• Low-side ignition FET gate driver
