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

V CC 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.

Ordering Information

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.
