    • Product Details

    The MAX8717 evaluation kit (EV kit) demonstrates the MAX8717's standard application circuit. This dual-PWM synchronous DC-DC converter steps down high-voltage batteries and/or AC adapters, generating main supplies for notebook computers.

    The MAX8717 EV kit provides dual 5V and 3.3V output voltages from the 6V to 24V battery input range. It delivers up to 5A output current for the 5V output and 5A for the 3.3V output with 95% efficiency. The EV kit operates at 300kHz switching frequency and has superior lineand load-transient response.

    This EV kit is a fully assembled and tested circuit board. Both outputs are adjustable between 1.0V and 5.5V by changing feedback resistors R20, R21, R24, and R26.

    Applications

    • 2 to 4 Li+ Cell Battery-Powered Devices
    • Main or I/O Power Supplies
    • Notebook and Subnotebook Computers
