The MAX17007 evaluation kit (EV kit) demonstrates the
standard 12A application circuit of the MAX17007. This
DC-DC converter steps down high-voltage batteries to
generate low-voltage core or chipset/RAM bias sup-
plies in notebook computers.
The default MAX17007 EV kit design provides two inde-
pendent outputs (OUT1 and OUT2) from a 7V to 24V
battery-input range. OUT1 is configured for a dynamic
1V/1.2V output voltage and OUT2 is configured to a
preset 1.5V output voltage. Each output delivers at least
12A. The OUT1 and OUT2 outputs operate at 270kHz
and 330kHz switching frequencies, respectively.
19-3125; Rev 0; 1/08
+ Denotes lead-free and RoHS-compliant.
