Evaluation Kit for the MAX1937, MAX1938, MAX1939 (MAX1938EVKIT) (MAX1938EVKIT)

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.
