Military 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)
