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
VCC 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.
