Compact, high efficiency, high power, half-brick DC-DC converters

SynQor, Inc., announces the latest additions to its Mil-COTS 28V (9-40 Vin) DC-DC product line: the MCOTS-C-28V-12-HY and MCOTS-C-28V-28-HY. These new compact, high efficiency, high power, half-brick DC-DC converters are based on SynQor's next-generation, isolated, fixed frequency synchronous rectifier technology. Given the topological restraints of modern power applications, the markedly impressive power density of these half-brick converters offers engineers more headroom and flexibility in designing power systems.

The MIL-STD-704 compliant power converters deliver a regulated output at either 12 or 28 Vdc respectively. This output voltage can be trimmed up to +10% via a trim resistor connected to the positive SENSE line and trimmed down to -50% if connected to the negative SENSE line. The units include a high output capacitive option that allows them to power loads with up to 1225 mF for the 12 Vdc output version and 225 mF for the 28 Vdc version. The units also include a built-in digital load-sharing feature allowing up to 100 units to load share in a system. These products are designed to maintain extremely high efficiencies while facilitating high-power conversion, which, in effect, enables designers to deliver full power to the load at baseplate temperatures as high as 100 °C given input voltages above 12 Vdc on account of the low dissipation characteristics of the modules. 

Designed with military standard compliance as a guiding tenet, the MCOTS-C-28V-12-HY and MCOTS-C-28V-28-HY are capable of operating in the harshest of military environments including ground-based, naval, and airborne applications. Additionally, the wide input range and impressive power density of the modules help optimize space in an industry where space is a critical consideration. SynQor's field-proven, highly reliable technology shortens design cycles and helps designers/integrators yield reliable, dependable solutions for the very competitive military markets.
