The MAX17039 evaluation kit (EV kit) demonstrates

the high-power, dynamically adjustable, multiphase

IMVP-7 notebook application circuit. This DC-DC con-

verter steps down high-voltage batteries and/or AC

adapters, generating two precision, low-voltage CPU/

GPU core rails. The EV kit meets the Intel mobile IMVP-7

CPU’s transient voltage specification, power-good sig-

naling, voltage regulator thermal monitoring (VR_HOT),

power-good outputs (VR__READY), and serial VID com-

munication and control specification. The MAX17039

consists of two high-current SMPSs for the CPU and

GPU cores. The CPU regulator is a 3-phase interleaved

Quick-PWMK architecture with one MAX8791 single-

synchronous MOSFET driver. The second GPU regulator

is also a 1-phase Quick-PWM architecture. The 3-phase

CPU core SMPS runs 120N out-of-phase for true inter-

leaved operation, minimizing input capacitance.

Both CPU/GPU output voltages are controlled indepen-

dently and are dynamically changed through a 3-wire

serial VID interface (3-wire SVID: VCLK, VDIO, ALERT),

allowing the switching regulators to be individually pro-

grammed to different voltages. The EV kit includes active

voltage positioning with adjustable gain, reducing power

dissipation and bulk output capacitance requirements. A

slew-rate controller allows controlled transitions among

VID codes, controlled soft-start, and shutdown. SVID

also allows each regulator to be individually set into a

low-power, pulse-skipping state.

The MAX17039 provides a digitally adjustable 0 to

1.5200V output-voltage range from a 7V to 20V battery-

input range. Each phase of the CPU core SMPS is

designed for a 20A thermal-design current and delivers

up to 33A peak output current for a total of 99A. The

1-phase GPU core SMPS is designed for 20A thermal-

design current and delivers up to 33A peak output cur-

rent. The CPU core SMPS operates at 350kHz switching

frequency (per phase) and has superior line- and load-

transient response. The GPU core SMPS operates at

440kHz switching frequency relative CPU core SMPS.

The MAX17039 EV kit also evaluates the MAX17000 and

MAX17007A DC-DC converters. The EV kit also includes

Windows

compatible software that provides a simple graphical

user interface (GUI) for exercising the features of the

MAX17039.
