Product Details

The MAX5037 evaluation (EV) kit is a fully assembled and tested VRM power-supply evaluation kit. The EV kit module can be inserted directly into the VRM daughter board AMP connector (1364125-1 or equivalent) on Pentium® 4 processor motherboards. The input voltage range is either 4.75V to 5.5V or 8V to 13.2V. The EV kit design is optimized for the best performance at 12V input and 1.75V output voltage settings. The output is programmable from 1.1V to 1.85V through VID input in compliance with Intel® VRM 9.0 specification. Up to 52A load current is possible from dual-phase conversion. High-power density and simple assembly is achieved due to a lower component count using the MAX5037.

Warning
The MAX5037 EV kit is designed to operate at high currents, and some of the components operate at high temperatures. Avoid touching the components. The evaluation board is not provided with a fuse. Use a controlled current source to power up the board. Under severe fault conditions, this EV kit may dissipate a large amount of power. To avoid possible personal injury, operate this kit with care.
