Product Details

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, generating a precision, low-voltage CPU core VCC rail. The MAX1717 EV kit meets the Intel mobile Pentium® III CPU's transient voltage specification by using voltage positioning to minimize output capacitor requirements.

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 output current with 14.1A peak current. The EV kit operates at 300kHz switching frequency and has superior line- and load-transient response. Output slew-rate control 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, providing “just-in-time” arrival at the new DAC setting.

Applications

  • 2-Cell to 4-Cell Li+ Battery to CPU Core Supply Converters
  • 5V to CPU Core Supply Converters
  • Notebook Computers with Intel SpeedStep® or Other Dynamically Adjustable Processors
