Evaluates: MAX17410 19-4441 Rev 0 1/09 MAX17410 Evaluation Kit General Description Features The MAX17410 evaluation kit (EV kit) demonstrates the Dual-Phase, Fast-Response Interleaved, Quick- high-power, dynamically adjustable, multiphase IMVP-6+ PWM notebook CPU application circuit. This DC-DC convert- Intel IMVP-6+ Code-Set Compliant er steps down high-voltage batteries and/or AC adapters, generating a precision, low-voltage CPU core Dynamic Phase Selection Optimizes Active/Sleep V rail. The MAX17410 EV kit meets the Intel mobile CC Efficiency IMVP-6+ CPUs transient voltage specification, power- Transient Phase Overlap Reduces Output good signaling, voltage regulator thermal monitoring (VRHOT), and power monitor output (PMON). The Capacitance MAX17410 EV kit consists of the MAX17410 2-phase Transient-Overshoot Suppression Feature interleaved Quick-PWM step-down controller. The MAX17410 EV kit includes active voltage positioning Active Voltage Positioning with Adjustable Gain with adjustable gain, reducing power dissipation, and High Speed, Accuracy, and Efficiency bulk output capacitance requirements. A slew-rate con- troller allows controlled transitions between VID codes, Low Bulk Output Capacitor Count controlled soft-start and shutdown, and controlled exit 7V to 24V Input-Voltage Range suspend voltage. Precision slew-rate control provides just-in-time arrival at the new DAC setting, minimizing 0 to 1.5000V Output-Voltage Range (7-Bit DAC) surge currents to and from the battery. 38A Load-Current Capability (19A per Phase) Dedicated system inputs (PSI, DPRSTP, and DPRSLPVR) Accurate Current Balance and Current Limit dynamically select the operating mode and number of active phases, optimizing the overall efficiency during 300kHz Switching Frequency (per Phase) the CPUs active and sleep states. Power-Good (PWRGD) and Phase-Good The MAX17410 includes latched output undervoltage- (PHASEGD) Outputs and Indicators fault, overvoltage-fault, and thermal-overload protec- tion. It also includes a voltage regulator power-good Clock Enable (CLKEN) and Thermal-Fault output (PWRGD), a clock enable output (CLKEN), a (VRHOT) Outputs and Indicators power monitor output (PMON), a phase-good output Lead(Pb)-Free and RoHS Compliant (PHASEGD), and a system power-good input (PGDN). Fully Assembled and Tested This fully assembled and tested circuit board provides a digitally adjustable 0 to 1.5000V output voltage (7-bit Ordering Information on-board DAC) from a 7V to 24V battery input range. Each phase delivers up to 19A output current for a total PART TYPE of 38A. The MAX17410 EV kit operates at 300kHz MAX17410EVKIT+ EV Kit switching frequency (per phase) and has superior line- +Denotes lead(Pb)-free and RoHS compliant. and load-transient response.
