The MAX17000 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed-circuit board (PCB) that demonstrates the MAX17000 DDR memory power solution. The EV kit provides the regulated voltages 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, generates a preset 1.8V VDDQ (OUT) main memory voltage that is capable of sourcing 10A. The termination regulator provides a 0.9V VTT supply that is capable of sinking/sourcing 2A. The termination reference buffer provides 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.
