The MCOTS-C-270-40-HE and MCOTS-C-270-60-HE join the MilQor® series of high-efficiency Mil-COTS DC-DC converters. MilQor® DC-DC converters bring SynQor’s field proven high-efficiency synchronous rectification technology to the Military/Aerospace industry.

SynQor’s ruggedized encased packaging approach ensures survivability in the most demanding environments. Compatible with the industry standard format, these converters operate at a fixed frequency, and follow conservative component derating guidelines, complying with a wide range of military standards. The MCOTS-C-270-40-HE and MCOTS-C-270-60-HE feature an adjustable current limit for powering near infinite capacitive loads or a battery. Other advanced features include serial communication for module configuration and monitoring, active current share for paralleling converters, external clock synchronization to improve EMI performance, and a battle short feature that overrides the over-temperature shutdown functionality in applications where the module needs to operate in conditions beyond the intended temperature range.
