    • Product Details

    The MAX1844 evaluation kit (EV kit) demonstrates the MAX1844’s standard 4A application circuit. This DC-DC converter steps down high-voltage batteries and/or AC adapters, generating a precision, low-voltage rail for use as chipset, DRAM, and other low-voltage supplies.

    The MAX1844 EV kit provides a 1.8V output voltage from a 7V to 24V battery input range. It delivers up to 4A output current with greater than 90% efficiency. The EV kit operates at 300kHz switching frequency and has superior line- and load-transient response.

    This EV kit is a fully assembled and tested circuit board. It also allows the evaluation of other output voltages in the 1.0V to 5.5V range by changing feedback resistors R1 and R2.

    Applications

    • 1.8V and 2.5V Supplies
    • Chipset/RAM Supplies as Low as 1V
    • CPU Core Supplies
    • Notebook Computers
