MCOTS DC-DC Bus Converters

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.
