Design files

Overview

The PMP8673 reference design is a synchronous boost converter optimized for high efficiency while maintaining a small form factor. This reference design has a voltage input range of 34.5-37.5V (35V nominal) and provides an output voltage of 55.5V. The synchronous boost topology enables efficiencies greater than 97% in the 2-3A load range. The switching frequency is set for 400Khz allowing the use of smaller external components and a total board area of less than 60 square centimeters.

Features
  • Efficiency >97% in a load range of 2A..3A
  • Ultra small with high power density
  • Adjustable output voltage from 38V to 55.5V
  • 150W output power
  • 200W hold up for 10ms
  • Output ripple < 0.5%
  • 90% transient response < 1%
  • Load regulation < 0.05%
  • With disconnection switch
