PCB Layout Guidelines
Careful PCB layout is critical to achieve low switching
losses and clean, stable operation. The switching
power stage requires particular attention. Follow these
guidelines for good PCB layout:
1) Place IC decoupling capacitors as close to the IC
pins as possible. Separate the power and analog
ground planes. Place the input ceramic decoupling
capacitor directly across and as close as possible
to IN and PGND. This is to help contain the high
switching current within this small loop.
4)
5)
6)
7)
Connect PGND, GND, and RTN at the return path
of the input bypass capacitor.
Signals shared by the master and slave (ILIM,
COMP, and FREQ) should not run close to switch-
ing signals.
Place the inductor current-sense resistor and
capacitor as close to the inductor as possible.
Make a Kelvin connection to minimize the effect of
PCB trace resistance.
Connect the exposed pad sections to the corre-
sponding IC pins and allow sufficient copper area
to help cooling the device.
2)
For output current greater than 10A, a four-layer
PCB is recommended. Pour an analog ground
8)
Place the REFIN and compensation components
as close to the IC pins as possible.
plane in the second layer underneath the IC to min-
imize noise coupling.
9) Connect remote-sense input RS+ and RS- directly
to the load voltage regulation point and use Kelvin
3)
Connect input and output capacitor to the PGND
plane and the VL capacitor to RTN. Connect all
analog signals to GND. The frequency-setting
capacitor should be connected to GFREQ.

10) Refer to the MAX8686 Evaluation Kit for an exam-
ple layout.
