描述
The MAX1637 evaluation kit (EV kit) contains two separate switching-regulator circuits. The first circuit converts high-voltage battery power into a low-voltage supply rail for next-generation notebook CPU cores. Its output is fixed at 1.7V and delivers up to 7A output current with greater than 87% efficiency. The second circuit generates a low-voltage supply for general-purpose use. Its output is fixed at 2.5V and delivers up to 3A output current. The battery range for both circuits is 4.5V to 22V, and both require a separate 5V input voltage to power the MAX1637. Output voltages can be adjusted by changing the feedback resistor values.
The MAX1637 EV kit has excellent dynamic response to correct for fast output transients. This EV kit is a fully assembled and tested circuit board.
