MAX15118
High-Efficiency, 18A, Current-Mode Synchronous
Step-Down Regulator with Integrated Switches
Power Dissipation
The MAX15118 is available in a 28-bump WLP package
and can dissipate up to 3.26W at T A = +70 N C. When
the die temperature exceeds +150 N C, the thermal shut-
down protection is activated (see the Thermal Shutdown
Protection section).
Layout Procedure
Careful PCB layout is critical to achieve clean and stable
operation. It is highly recommended to duplicate the
MAX15118 Evaluation Kit (EV kit) layout for optimum
performance. The MAX15118 EV kit board has a small,
quiet, ground-shape SGND on the back side below the
IC. This ground is the return for the control circuitry,
especially the return of the compensation components.
This SGND is returned to the IC ground through vias
close to the ground bumps of the IC. If deviation is nec-
essary, follow these guidelines for good PCB layout:
1) Connect a single ground plane immediately adjacent
to the GND bumps of the IC.
2) Place capacitors on IN and SS/REFIN as close as
possible to the IC and the corresponding pad using
direct traces.
3) Keep the high-current paths as short and wide as

Package Information
For the latest package outline information and land patterns
(footprints), go to www.maxim-ic.com/packages . Note that a
“+”, “#”, or “-” in the package code indicates RoHS status only.
Package drawings may show a different suffix character, but
the drawing pertains to the package regardless of RoHS status.

possible. Keep the path of switching current short
and minimize the loop area formed by LX, the output
capacitors, and the input capacitors.
4) An electrolytic capacitor is strongly recommended for
damping when there is significant distance between
the input power supply and the MAX15118.
5) Connect IN, LX, and GND separately to a large cop-
per area to help cool the IC to further improve effi-
ciency.
6) Ensure all feedback connections are short and direct.
Place the feedback resistors and compensation com-
ponents as close as possible to the IC.
7) Route high-speed switching nodes (such as LX
and BST) away from sensitive analog areas (such as
FB and COMP).
