Description
Mil-COTS Unregulated 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. The Mil-COTS series provides an isolated step-down voltage from 270V or 600V to 31V intermediate bus with no regulation in a standard half-brick module. 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 up to 65A @ full power with minimal derating
- Operating input voltage range: 230-400V, 440-700V, and 800-1000V
- Fixed frequency switching provides predictable EMI
- Industry-standard half-brick pin-out configuration
- -55°C to +100°C Operating Temperature
Protection
- 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)
