Product Details

The MAXM17625/MAXM17626 evaluation kits (EV kits) provide a proven design to evaluate the performance of the MAXM17625/MAXM17626 modules. Each of these modules are configured to demonstrate optimum performance and component sizes in the EV kits.

The MAXM17625 module delivers up to 600mA at a switching frequency of 2MHz. The module is configured for a 1.5V output over a 2.7V to 5.5V input range.

The MAXM17626 module delivers up to 600mA at a switching frequency of 4MHz. The module is configured for a 3.3V output over a 3.6V to 5.5V input range.

The EV kits feature provisions for selecting Mode of operation (PWM/PFM) and Enable input. The MAXM17625/MAXM17626 module data sheet provides a complete description of the parts that should be read in conjunction with this data sheet prior to operating the EV kits.

Applications

  • Battery Powered Applications
  • Distributed Power Systems
  • Industrial Sensors and Process Control
  • Point-of-Load Power Supply
  • Standard 5V Rail Supplies
