The MAX8529 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board demonstrating
the MAX8529 dual, synchronized, step-down controller.
The EV kit comes assembled with a circuit that steps
down from an 8V to 13.2V input voltage, to output voltages
of 1.8V and 3.3V. Both are capable of sourcing
3A. The switching frequency is set at 1.2MHz, and is
adjustable from 600kHz to 1.5MHz with an external
resistor. Alternatively, the controller can be synchronized
to an external clock generated by another
MAX8529 or a system clock. This device also features
soft-start and soft-stop. The MAX8529 eliminates the
need for current-sense resistors by utilizing the low-side
MOSFET's on-resistance as the current-sense element.
The adjustable foldback current limit reduces power
dissipation during short-circuit conditions. The
MAX8529 includes a power-on reset output to signal
the system when both outputs reach regulation.
