3) Group the gate-drive components (BST capacitors,
V DD bypass capacitor) together near the controller IC.
4) Make the DC-DC controller ground connections as
shown in Figures 1 and 2. This diagram can be
viewed as having four separate ground planes: I/O
ground, where all the high-power components go;
the power ground plane, where the PGND pin and
V DD bypass capacitor go; the master ’s analog
ground plane where sensitive analog components,
the master’s GND pin, and V CC bypass capacitor
go; and the slave’s analog ground plane where the
slave’s GND pin and V CC bypass capacitor go. The
master’s GND plane must meet the PGND plane
only at a single point directly beneath the IC.
Similarly, the slave ’s GND plane must meet the
PGND plane only at a single point directly beneath
POWER STAGE LAYOUT (TOP SIDE OF PCB)
the IC. The respective master and slave ground
planes should connect to the high-power output
ground with a short metal trace from PGND 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 (V OUT 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 load as is practical. See Figure 15.
