    • Product Details

    The MAX1845 evaluation kit (EV kit) demonstrates the MAX1845’s standard application circuit. This DC-DC converter steps down high-voltage batteries and/or AC adapters, generating precision, low-voltage rails for use as chipset, DRAM supplies, CPU core, and IO supplies.

    The MAX1845 EV kit provides dual 1.8V and 2.5V output voltages from a 7V to 22V battery input range. It delivers up to 4A output current for the 2.5V output and 7A for the 1.8V output, with greater than 90% efficiency. The EV kit operates at 255kHz/345kHz 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–R4.

    Applications

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