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.
x Separate analog bus (EAIN, DACIN, and IOUT) from digital bus (CLKIN, PSI, PHSIN, and PHSOUT) to
reduce the noise coupling.
x Place current sense resistors and capacitors (R CS and C CS ) close to phase IC. Use Kelvin connection for
the 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.
x Place the decoupling capacitors C VCC and C VCCL as close as possible to VCC and VCCL pins of the
phase IC respectively.
x Place the phase IC as close as possible to the MOSFETs to reduce the parasitic resistance and
inductance of the gate drive paths.
x Place the input ceramic capacitors close to the drain of top MOSFET and the source of bottom MOSFET.
Use combination of different packages of ceramic capacitors.
x There are four switching power loops. Two loops include the input capacitors, top MOSFET, inductor,
output capacitors and the load; two other loops consist of bottom MOSFET, inductor, output capacitors and
the load. Route the switching power paths using wide and short traces or polygons; use multiple vias for
connections between layers.
