    Description

    The MAX1999 evaluation kit (EV kit) demonstrates the MAX1999's standard application circuit. This DC-DC converter steps down high-voltage batteries and/or AC adapters, generating system supplies for notebook computers. The MAX1999 EV kit provides dual 5V and 3.3V output voltages from a 7V to 24V battery input range. It delivers up to 5A output current for the 5V output and 5A for the 3.3V output with greater than 90% efficiency. The EV kit operates at 200kHz/300kHz switching frequency (5V/3.3V, respectively) and has superior line-and-load- transient response.

    This EV kit is a fully assembled and tested circuit board. It allows the evaluation of other output voltages in the 2V to 5.5V range by changing feedback resistors R1-R4.

    This EV kit can also be used to evaluate the MAX1777 (200kHz/5.0V SMPS and 300kHz/3.3V SMPS) and the MAX1977 (400kHz/5.0V SMPS and 500kHz/3.3V SMPS).
