Product Details

The MAX17582 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-voltage CPU core VCC rail. The MAX17582 EV kit meets the Intel mobile IMVP-6.5 CPU's transient voltage specification, power-good signaling, voltage regulator thermal monitoring (active-low VRHOT), and power-good output (PWRGD). The MAX17582 EV kit consists of the MAX17582 2-phase interleaved Quick-PWM™ step-down controller. The MAX17582 EV kit includes active voltage positioning 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 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.

Two dedicated system inputs (active-low 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 MAX17582 includes latched-output undervoltage-fault, overvoltage-fault, and thermal-overload protection. It also includes a voltage regulator power-good (PWRGD) output, a clock enable (active-low CLKEN) output, a current monitor output (IMON), 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 current, and delivers up to 30A peak output current for a total of 60A. The MAX17582 EV kit operates at 300kHz switching frequency (per phase) and has superior line- and load-transient response.
