The MAX1938 evaluation kit (EV kit) is a fully tested and
assembled power supply that demonstrates the full
functionality of the MAX1937/MAX1938/MAX1939 family
of synchronous, two-phase, step-down controllers. The
circuit operates from an input supply range of 8V to 14V
and provides VID-controlled CPU core voltage with up
to 60A of output current. The EV kit comes with the
MAX1938 installed, which provides a 5-bit VID code
interface to meet Intel Voltage-Regulator Module (VRM)
9.0/9.1 specifications. The MAX1937 and MAX1939 can
also be evaluated using the same board by replacing
the MAX1938. The MAX1937 supports the AMD
Hammer CPU VID codes, and the MAX1939 supports
the AMD Athlon® Mobile CPU VID codes.
