LAYOUT GUIDELINES

The following layout guidelines are recommended to reduce the parasitic inductance and resistance of the PCB

layout, therefore minimizing the noise coupled to the IC.

•

Dedicate at least one middle layer for a ground plane LGND.

Connect the ground tab under the control IC to LGND plane through a via.

Place the following critical components on the same layer as control IC and position them as close as

possible to the respective pins, ROSC, ROCSET, RVDAC, CVDAC, CVCC, CSS/DEL and RCC/DEL. Avoid using any

via for the connection.

•

Place the compensation components on the same layer as control IC and position them as close as possible

to EAOUT, FB and VDRP pins. Avoid using any via for the connection.

Use Kelvin connections for the remote voltage sense signals, VOSNS+ and VOSNS−, and avoid crossing

over the fast transition nodes, i.e. switching nodes, gate drive signals and bootstrap nodes.

Control bus signals, VDAC, RMPOUT, IIN, VBIAS, and especially EAOUT, should not cross over the fast

transition nodes.

METAL AND SOLDER RESIST

• The solder resist should be pulled away from the metal lead lands by a minimum of 0.06mm. The

solder resist mis−alignment is a maximum of 0.05mm and it is recommended that the lead lands are

all Non Solder Mask Defined (NSMD). Therefore pulling the S/R 0.06mm will always ensure NSMD

pads.

• The minimum solder resist width is 0.13mm, therefore it is recommended that the solder resist is

completely removed from between the lead lands forming a single opening for each “group” of lead

lands.

• At the inside corner of the solder resist where the lead land groups meet, it is recommended to

provide a fillet so a solder resist width of ≥ 0.17mm remains.

• The land pad should be Solder Mask Defined (SMD), with a minimum overlap of the solder resist onto

the copper of 0.06mm to accommodate solder resist mis−alignment. In 0.5mm pitch cases it is

allowable to have the solder resist opening for the land pad to be smaller than the part pad.

• Ensure that the solder resist in−between the lead lands and the pad land is ≥ 0.15mm due to the high

aspect ratio of the solder resist strip separating the lead lands from the pad land.

• The single via in the land pad should be tented with solder resist 0.4mm diameter, or 0.1mm larger

than the diameter of the via.

IR3084

PCB METAL AND COMPONENT PLACEMENT

• Lead land width should be equal to nominal part lead width. The minimum lead to lead spacing

should be ≥ 0.2mm to minimize shorting.

• Lead land length should be equal to maximum part lead length + 0.2 mm outboard extension +

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.

• Center pad land length and width should be equal to maximum part pad length and width. However,

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)

• A single 0.30mm diameter via shall be placed in the center of the pad land and connected to ground

to minimize the noise effect on the IC.

IR3084

STENCIL DESIGN

• The stencil apertures for the lead lands should be approximately 80% of the area of the lead lands.

Reducing the amount of solder deposited will minimize the occurrence of lead shorts. Since for

0.5mm pitch devices the leads are only 0.25mm wide, the stencil apertures should not be made

narrower; openings in stencils < 0.25mm wide are difficult to maintain repeatable solder release.

• The stencil lead land apertures should therefore be shortened in length by 80% and centered on the

lead land.

• The land pad aperture should be striped with 0.25mm wide openings and spaces to deposit

approximately 50% area of solder on the center pad. If too much solder is deposited on the center

pad the part will float and the lead lands will be open.

• The maximum length and width of the land pad stencil aperture should be equal to the solder resist

opening minus an annular 0.2mm pull back to decrease the incidence of shorting the center land to

the lead lands when the part is pushed into the solder paste.
