MAX15112
High-Efficiency, 12A, Current-Mode Synchronous
Step-Down Regulator with Integrated Switches
Power Dissipation
The MAX15112 is available in a 24-bump WLP package
and can dissipate up to 2.15W at +70 N C board tem-
perature. When the die temperature exceeds +150 N C,
the thermal shutdown 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
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).
Ordering Information
MAX15112 Evaluation Kit layout for optimum perfor-
mance. The MAX15112 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 necessary, 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
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 MAX15112.
5) Connect IN, LX, and GND separately to a large copper
