MAX17030 Evaluation Kit
General Description
The MAX17030 evaluation kit (EV kit) demonstrates the
high-power, dynamically adjustable, multiphase IMVP-
6.5 notebook CPU application circuit. This DC-DC con-
verter steps down high-voltage batteries and/or AC
adapters, generating a precision, low-voltage CPU core
V
CC
rail. The MAX17030 EV kit meets the Intel mobile
IMVP-6.5 CPU’s transient voltage specification, power-
good signaling, voltage regulator thermal monitoring
(VRHOT), and power-good output (PWRGD). The
MAX17030 EV kit consists of the MAX17030 3-phase
interleaved Quick-PWM™ step-down controller and one
external MAX8791 single synchronous MOSFET driver.
The MAX17030 EV kit includes active voltage position-
ing with adjustable gain, reducing power dissipation
and bulk output capacitance requirements. A slew-rate
controller allows controlled transitions between VID
codes, controlled soft-start and shutdown, and con-
trolled exit suspend voltage. Precision slew-rate control
provides “just-in-time” arrival at the new DAC setting,
minimizing surge currents to and from the battery.
Two dedicated system inputs (PSI and DPRSLPVR)
dynamically select the operating mode and number of
active phases, optimizing the overall efficiency during
the CPU’s active and sleep states.
The MAX17030 includes latched output undervoltage-
fault protection, overvoltage-fault protection, and ther-
mal-overload protection. It also includes a voltage regu-
lator power-good (PWRGD) output, a clock enable
(CLKEN) output, and a current monitor (IMON) output.
The MAX17030 provides a digitally adjustable 0 to
1.5000V output voltage (7-bit on-board DAC) from a 7V
to 20V battery-input range. Each phase is designed for
a 20A thermal design current, and delivers up to 22A
peak output current for a total of 66A. The EV kit oper-
ates at 300kHz switching frequency (per phase) and
has superior line- and load-transient response.
The MAX17030 EV kit also evaluates the MAX17000,
MAX17007A, and MAX17028 DC-DC converters.

MAX17030 EV kit
7V to 20V power supply, battery, or notebook AC
adapter
DC bias power supply, 5V at 1A
DC bias power supply, 3.3V at 100mA
Three dummy loads capable of sinking 22A each
Digital multimeters (DMMs)
100MHz dual-trace oscilloscope
Set SW1 (2, 13), SW1 (4, 11), and SW1 (6, 9) to the
on positions. Set SW4 (1, 8) and SW5 (4, 5) to the
on positions.The output voltage is set for 0.9750V.
3) Turn on the battery power before turning on the 5V
bias power. Turn on the 5V and 3.3V power supplies.
4) Observe the 0.9750V output voltage with the DMM
and/or oscilloscope. Look at the LX switching nodes
and MOSFET gate-drive signals while varying the
load current.
Detailed Description of Hardware
Procedure
This 66A multiphase buck-regulator design is optimized
for a 300kHz switching frequency (per phase) and out-
put-voltage settings around 1V. At V
OUT
= 1V and V
IN
= 12V, the inductor ripple is approximately 30% (LIR =
0.30). The MAX17030 controller interleaves all the
active phases, resulting in out-of-phase operation that
minimizes the input and output filtering requirements.
The multiphase controller shares the current between
three phases that operate 120° out-of-phase, supplying
up to 22A per phase.
The MAX17030 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Ensure that the circuit is connected correctly to the
supplies and dummy load prior to applying any
power.
2) Verify that all positions of switch SW2 are off. The
DAC code settings (D6–D0) are set by switch SW1.
