Product Details

The MAX15034B evaluation kit (EV kit) is a two-phase, dual-output buck converter with a 5V to 16V input voltage range. The MAX15034B EV kit provides dual 1.2V output voltages (VOUT1 and VOUT2). It delivers up to 20A output current for each output with 86.7% efficiency. The MAX15034B EV kit uses average current-mode control and operates at 300kHz switching frequency per phase where each phase is 180° out-of-phase with respect to the other.

The MAX15034B EV kit is a fully assembled and tested circuit board. Both outputs are adjustable between 0.61V and 5.5V by changing feedback resistors R4–R7. Additional features include thermal-shutdown and "hiccup-mode" short-circuit protection.

Applications

  • Graphics Cards
  • High-End Computers/Workstations/Servers
  • Networking Systems
  • Point-of-Load High-Current/High-Density Telecom DC-DC Regulators
  • RAID Systems
