MAX17410 Evaluation Kit

General Description

The MAX17410 evaluation kit (EV kit) demonstrates the

high-power, dynamically adjustable, multiphase IMVP-6+

notebook CPU application circuit. This DC-DC convert-

er steps down high-voltage batteries and/or AC

adapters, generating a precision, low-voltage CPU core

VCC rail. The MAX17410 EV kit meets the Intel mobile

IMVP-6+ CPU’s transient voltage specification, power-

good signaling, voltage regulator thermal monitoring

(VRHOT), and power monitor output (PMON). The

MAX17410 EV kit consists of the MAX17410 2-phase

interleaved Quick-PWM™ step-down controller. The

MAX17410 EV kit includes active voltage positioning

with adjustable gain, reducing power dissipation, and

bulk output capacitance requirements. A slew-rate con-

troller allows controlled transitions between VID codes,

controlled soft-start and shutdown, and controlled 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.

Dedicated system inputs (PSI, DPRSTP, 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 MAX17410 includes latched output undervoltage-

fault, overvoltage-fault, and thermal-overload protec-

tion. It also includes a voltage regulator power-good

output (PWRGD), a clock enable output (CLKEN), a

power monitor output (PMON), a phase-good output

(PHASEGD), and a system power-good input (PGDN).

This fully assembled and tested circuit board provides

a digitally adjustable 0 to 1.5000V output voltage (7-bit

on-board DAC) from a 7V to 24V battery input range.

Each phase delivers up to 19A output current for a total

of 38A. The MAX17410 EV kit operates at 300kHz

switching frequency (per phase) and has superior line-

and load-transient response.
