24V to 5V@4A Reference Design for Industrial Robots and Motor Drives


Design files


The PMP15025 comprises a single phase synchronous buck converter that supplies a stable 5V @ 4A solution from a 24V input. The design features high efficiency and power density, which are suitable for industrial automation applications, such as robotics and motor drives.

  • 90% efficiency at 24VIN, 5V/4A at 390kHz
  • 4.44mV of Output Ripple at full load current
  • Minimal Phase Ringing at full load current
  • 30kHz Loop Bandwidth with 75° of Phase Margin for fast, stable, transient response
