Pin Configurations
Layout Procedure
1) Place the power components first, with ground termi-
nals adjacent (Q2 source, CIN-, COUT-, D1 anode). If
possible, make all these connections on the top layer
with wide, copper-filled areas.
2) Mount the controller IC adjacent to MOSFET Q2,
preferably on the back side opposite Q2 in order to
keep LX-PGND current-sense lines and the DL gate-
drive line short and wide. The DL gate trace must be
short and wide, measuring 10 to 20 squares (50 to
100 mils wide if the MOSFET is 1 inch from the con-
troller IC).
3) Group the gate-drive components (BST diode and
capacitor, V
DD
bypass capacitor) together near the
controller IC.
4) Make the DC-DC controller ground connections as
shown in Figure 11. This diagram can be viewed as
having three separate ground planes: output ground,
where all the high-power components go; the PGND
plane, where the PGND pin and V
DD
bypass capaci-
tor go; and an analog GND plane, where sensitive
analog components go. The analog ground plane
and PGND plane must meet only at a single point
directly beneath the IC. These two planes are then
connected to the high-power output ground with a
short connection from V
DD
cap/PGND to the source
of the low-side MOSFET, Q2 (the middle of the star
ground). This point must also be very close to the out-
put capacitor ground terminal.
5) Connect the output power planes (V
CORE
and system
ground planes) directly to the output filter capacitor
positive and negative terminals with multiple vias.
Place the entire DC-DC converter circuit as close to
the CPU as is practical.
