Overview

DC-DC Bus Converters

Mil-COTS Rugged, High Efficiency Next Generation DC-DC Bus Converters

These military-grade bus converters are the next-generation, board-mountable, isolated, fixed switching frequency DC‑DC converters that use synchronous rectification to achieve extremely high conversion efficiency. MCOTS Bus converters are ideal for creating the mid-bus voltage required to drive point-of-load (non-isolated) converters in Intermediate Bus Architectures.

Operational Features

  • High efficiency, up to 95% at full rated load current
  • Delivers 32 A full power with minimal derating
  • Operating input voltage range: 230-400 V and 440-700 V
  • Fixed frequency switching provides predictable EMI
  • No minimum load requirement
  • Industry standard half-brick pin-out configuration
  • -55°C to +100°C Operating Temperature

Protection/Control Features

  • Input under-voltage and over voltage lockout protects against abnormal input voltages
  • Output current limit and short circuit protection (auto recovery)
  • Thermal shutdown
  • On/Off control referenced to input side
  • Inherent current share (by droop method) for high current and parallel applications
  • Clock synchronization (primary reference)
