Key Document


This is a 24-A DC/DC space power hardware reference design.

As FPGA and ASIC technology advances, the core voltage requirements get lower but the current demand is larger. The newest space grade FPGAs and ASICS require low voltage and high currents for their core power consumption. These high current requirements drive a need for space grade DC/DC power conversion circuitry.

  • Stand-alone space rated clock generation
  • Multiple configurations to evaluate current sharing of 2, 3 or 4 TPS50601A-SP POLs
  • Built-in current sense monitoring
