• Manufacturer Part Number: ir3084u
• Description: Xphasetm Vr10, Vr11 & Opteron/athlon64 Control Ic
• Manufacturer: International Rectifier Corp.

PCB METAL AND COMPONENT PLACEMENT
• Lead land width should be equal to nominal part lead width. The minimum lead to lead spacing
• Lead land length should be equal to maximum part lead length + 0.2 mm outboard extension +
• Center pad land length and width should be equal to maximum part pad length and width. However,
• A single 0.30mm diameter via shall be placed in the center of the pad land and connected to ground
should be ≥ 0.2mm to minimize shorting.
0.05mm inboard extension. The outboard extension ensures a large and inspectable toe fillet, and
the inboard extension will accommodate any part misalignment and ensure a fillet.
the minimum metal to metal spacing should be ≥ 0.17mm for 2 oz. Copper (≥ 0.1mm for 1 oz. Copper
and ≥ 0.23mm for 3 oz. Copper)
to minimize the noise effect on the IC.
