Product Details

The MAX17083 evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the typical 5A application circuit of the MAX17083. The MAX17083 is a DC-DC converter that steps down the system's 3.3V or 5V input supply for low-voltage, low-power applications.

The MAX17083 EV kit provides a 1.1V output voltage from a 2.4V to 5.5V input range. It delivers up to 5A output current while achieving greater than 90% efficiency. Programmed through jumper JU4, the EV kit operates at 1MHz switching frequency and has superior line- and load-transient response. The EV kit also allows the evaluation of other adjustable output voltages from 0.75V to 2.7V, by varying the SET pin and changing resistors R3 and R4.

Applications

  • Low-Power Architectures
  • Netbook and Nettop PCs
  • Notebook and Subnotebook Computers
  • PDAs and Mobile Communicators
  • Portable Gaming
  • Ultra-Mobile PCs
