MAX17000EVKIT+

P1-P3P4-P6P7-P9P10-P11
General Description
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.

Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
• 5V, 100mA DC power supply (VDD)
• 7V to 20V, 5A DC power supply (IN)
• Voltmeter
Procedure
The MAX17000 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supplies until all
connections are completed.
1) Verify that the jumpers follow the default settings in
Table 1.
2) Connect the positive terminal of the VDD power
supply to the VDD pad. Connect the negative termi-
nal of the VDD power supply to the AGND pad.
3) Connect the positive terminal of the IN power sup-
ply to the IN pad. Connect the negative terminal of
the IN power supply to the PGND pad.
4) Set the IN power supply to 12V.
5) Set the VDD power supply to 5V.
6) Turn on the IN power supply before turning on the
VDD power supply.
7) Verify that the VDDQ output (OUT) is approximately
1.8V.
8) Verify that the termination power-supply output
(VTT) is approximately 0.9V.
9) Verify that the termination reference buffer output
(VTTR) is approximately 0.9V.

Detailed Description of Hardware
Jumper Selection
Several jumper settings in the following tables illustrate
features of the MAX17000 EV kit. Refer to the
MAX17000 IC data sheet for a more detailed descrip-
tion of each function.
OVP Mode Control (OVP)
The MAX17000 EV kit features a 2-pin jumper (JU1) to
enable or disable the SMPS overvoltage protection
(OVP) feature and output-discharge mode. By default
(JU1 = open), the OVP input pin is pulled high to VDD
through R4. The default setting enables the SMPS OVP.
Place a shunt on JU1 to disable the SMPS OVP. Select
the JU1 settings to drive the OVP mode control as
shown in Table 2.
Feedback Input (FB)
The MAX17000 EV kit provides a 3-pin jumper (JU2) to
control the feedback input (FB), which sets the V
DDQ
(OUT) output voltage. Place a shunt across pins 1-2
(default) for a fixed 1.8V output or across pins 2-3 for a
fixed 1.5V output. For an adjustable output (1V to 2.7V),
uninstall the JU2 shunt and connect FB to a resistive
divider from the output voltage. Install feedback resis-
tors with values according to the following equation:
where V
FB
= 1V. Use 10kΩ for R15, and calculate R14
for the desired output voltage. Table 3 summarizes
jumper JU2’s function.
Standby Control Input (
STDBY
) and
Shutdown Control Input (
SHDN
)
The EV kit features independent standby and shutdown
controls by implementing jumpers JU3 and JU5 to con-
trol the STDBY and SHDN inputs, respectively. Jumpers
JU3 and JU5 allow flexible sequencing to support all
DDR operating states. The shutdown and standby con-
trol logic is illustrated in Table 4.
