4) Make the DC-DC controller ground connections as

shown in the standard application circuits. This dia-

gram can be viewed as having four separate ground

planes: input/output ground, where all the high-

power components go; the power ground plane,

where the GND pin and VDD bypass capacitor go;

the master’s analog ground plane, where sensitive

analog components, the master’s GND pin and VCC

bypass capacitor go; and the slave’s analog ground

plane, where the slave’s GND pin and VCC bypass

capacitor go. The master’s GND plane must meet

the GND plane only at a single point directly

beneath the IC. Similarly, the slave’s GND plane

must meet the GND plane only at a single point

directly beneath the IC. The respective master and

slave ground planes should connect to the high-

power output ground with a short metal trace from

GND to the source of the low-side MOSFET (the

middle of the star ground). This point must also be

very close to the output capacitor ground terminal.

5) Connect the output power planes (VCORE and sys-

tem ground planes) directly to the output filter

capacitor positive and negative terminals with multi-

ple vias. Place the entire DC-DC converter circuit as

close to the CPU as is practical.
