MAX17021 Evaluation Kit
General Description
The MAX17021 evaluation kit (EV kit) demonstrates the
high-power, dynamically adjustable, multiphase
IMVP-6.5+ notebook CPU application circuit. This
DC-DC converter steps down high-voltage batteries
and/or AC adapters, generating a precision, low-volt-
age CPU core V CC rail. The MAX17021 EV kit meets the
Intel mobile IMVP-6+ CPU’s transient voltage specifica-
tion, power-good signaling, voltage regulator thermal
monitoring ( VRHOT ), and power-good output
(PWRGD). The MAX17021 kit consists of the MAX17021
2-phase interleaved Quick-PWM ? step-down con-
troller. The MAX17021 kit includes active voltage posi-
tioning 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 MAX17021 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 phase-good (PHASEGD) output.
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 is designed for a 20A thermal design cur-
