The MAX8664 evaluation kit (EV kit) is a fully assembled
and tested circuit for evaluating the MAX8664A/
MAX8664B dual-output step-down controllers. The
MAX8664 EV kit operates with a 600kHz switching fre-
quency and is optimized for operation from a 10.8V to
13.2V supply. The EV kit can operate down to 4.5V with
minor changes. The two step-down outputs provide up
to 8A each at 2.5V for OUT1 and 1.8V for OUT2.
Options are provided for sequencing or tracking of
OUT2. The MAX8664A (independent fault action)
comes installed in the EV kit and it can be replaced
with the MAX8664B (joint fault action) with no other
required component changes.
