Space-grade 3U VPX power supply module reference design

TIDA-011004

Design files

Overview

This reference design is a space-grade power supply module compliant with the VITA-62 standard for space-rated 3U VPX architectures. The Space VPX standard enables standardization and interoperability by defining a framework for modular and scalable systems that can be used in a variety of different mission profiles. This reference design is implemented with a compact form factor while maintaining a high overall performance.

Features
  • 300W Power supply module with nominal 28V input voltage
  • Output voltage rails: 12V at 18A, 5V at 12A, and 3.3V at 3A
  • Overcurrent protection on each output rail, temperature sensing, and microcontroller on board
  • Follows mechanical requirements of VITA62 standard and includes VPX power connector on board
  • Dimensions: 3U space VPX form factor (100mm × 160mm)
