The MAX17000 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount printed-circuit board
(PCB) that demonstrates the MAX17000 DDR memory
power solution. The EV kit provides the regulated volt-
ages required in a complete DDR memory system. The
EV kit generates the main memory voltage (VDDQ), the
tracking sinking/sourcing termination voltage (VTT), and
the reference voltage (VTTR).
The switch-mode power-supply (SMPS) regulator,
which operates at 300kHz switching frequency, gener-
ates a preset 1.8V VDDQ (OUT) main memory voltage
that is capable of sourcing 10A. The termination regula-
tor provides a 0.9V VTT supply that is capable of sink-
ing/sourcing 2A. The termination reference buffer pro-
vides a 0.9V VTTR supply that is capable of
sinking/sourcing 3mA.
The EV kit requires an input voltage source of 7V to 20V
(IN) and a low-power 5V (VDD) biasing supply.
