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, which is then split into signal ground plane (LGND) and
power ground plane (PGND).
? Connect PGND to LGND pins of each phase IC to the ground tab, which is tied to LGND and PGND planes
respectively through vias.
? In order to reduce the noise coupled to SCOMP pin of phase IC, use a dedicated wire to connect the capacitor
C SCOMP directly to LGND pin. However, connect PWM ramp capacitor C PWMRMP , phase delay programming
resistor R PHASE2 or R PHASE3, decoupling capacitor C VCC to LGND plane through vias.
? Place current sense resistors and capacitors (R CS+ , R CS- , C 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 RCS- should not cross over the fast transition nodes, i.e. switching nodes, gate drive
outputs and bootstrap nodes.
? Place the decoupling capacitors C VCC and C VCCL as close as possible to VCC and VCCL pins of the phase IC
respectively.
? Place the phase IC as close as possible to the MOSFETs to reduce the parasitic resistance and inductance of
the gate drive paths.
? 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.
? There are two switching power loops. One loop includes the input capacitors, top MOSFET, inductor, output
capacitors and the load; another loop consists 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.
