MAX1717 Evaluation Kit  
General Description  
Features  
High Speed, Accuracy, and Efficiency  
Voltage-Positioned Output  
The MAX1717 evaluation kit (EV kit) demonstrates a  
high-power, dynamically adjustable notebook CPU  
application circuit. The MAX1717 DC-DC converter  
steps down high-voltage batteries and/or AC adapters,  
Lowest Output Capacitor Count (4)  
Reduces CPU Power Consumption  
generating a precision, low-voltage CPU core V  
rail.  
CC  
The MAX1717 EV kit meets the Intel mobile Pentium® III  
CPU’s transient voltage specification by using voltage  
positioning to minimize output capacitor requirements.  
Fast-Response Quick-PWMArchitecture  
7V to 24V Input Voltage Range  
This fully assembled and tested circuit board provides  
a digitally adjustable 0.925V to 2V output voltage from a  
7V to 24V battery input range. It delivers up to 12A out-  
put current with 14.1A peak current. The EV kit oper-  
ates at 300kHz switching frequency and has superior  
line- and load-transient response. Output slew-rate con-  
trol minimizes battery and inductor surge currents. With  
its precision timer circuit, the MAX1717’s output voltage  
slew rate can be tailored to a given application, provid-  
ing “just-in-time” arrival at the new DAC setting.
