NEX40400EVM-05: 4.5 V to 40 V, 600 mA, FPWM, 1.05 MHz, synchronous step-down converter evaluation board

The NEX40400EVM-05 evaluation board is a reference design of a step down DC-DC switching voltage converter, assembled on a two-layer PCB. It enables testing of the functionality and performance of the NEX40400 buck converter.

Key features and benefits

  • 4.5V to to 40V input voltage range
  • 600mA continuous output current
  • 5V output
  • 1.05 MHz switching frequency Forced PWM operation
  • Frequency foldback for high conversion ratio and low drop-out application
  • Internal compensation
  • Short circuit protection with Hiccup mode
