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.
• Separate analog bus (EAIN, DACIN and ISHARE) from digital bus (CLKIN, PHSIN, and PHSOUT) to
• Connect PGND to LGND pins to the ground plane through vias
• Place current sense resistors and capacitors (R
• Place the IC, gate drive side as close as possible to the MOSFETs to reduce the parasitic resistance and
• Place the input ceramic capacitors close to the drain of top MOSFET and the source of bottom MOSFET.
reduce the noise coupling.
inductor current sense wires, but separate the two wires by ground polygon. The wire from the inductor
terminal to CSIN- should not cross over the fast transition nodes, i.e. switching nodes, gate drive outputs
and bootstrap nodes.
