  • Product Details

    The MAX1813 evaluation kit (EV kit) demonstrates the high-power, dynamically adjustable 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 MAX1813 EV kit meets the Intel® mobile CPU's transient voltage specification (IMVP-II/Coppermine), using voltage positioning to minimize the output-capacitor requirements. The MAX1813 has an internal multiplexer which accepts three unique 5-bit VID DAC codes corresponding to performance, battery, and suspend modes. Precision slew-rate control provides "just-in-time" arrival at the new DAC setting, minimizing surge currents to and from the battery.

    This fully assembled and tested circuit board provides a digitally adjustable 0.6V to 2.0V output from a 7V to 24V battery input range. It delivers up to 22A output current. The EV kit operates at 300kHz switching frequency and has superior line- and load-transient response.
