The high power density half-brick, quarter-brick and sixteenth-brick packages are fully encased and have industry standard footprints and pinout configurations. Although these efficient designs do not require a heatsink, the encased package will accommodate standard dc/dc converter heatsinks. A flanged baseplate version is also available.

The Mil-COTS 28 series undergo stringent qualification and characterization, with full component traceability and unique part serialization and are designed to conservative component derating guidelines. These converters are available in two options, an S-Grade or a more extensive M-Grade screening.

Fourteen output voltages from 1.2V to 50V have an adjustable trim from +10% to -20% (+/-10% for sixteenth-brick) to meet numerous application requirements. The fixed switching frequency design yields predictable EMI filtering and, when used in conjunction with a Mil-COTS EMI filter, differential mode noise is attenuated by more than 80dB and common-mode noise is attenuated by more than 36dB.

Protection features include input under-voltage lockout, output current limit and short circuit protection, active back-bias limit, output over-voltage protection and thermal shutdown. All models have at least 2250Vdc isolation rating between input and output, are rated with MTBF values in excess of 1MHrs at a baseplate temperature of 70°C.

The Mil-COTS 28 series of products are available immediately from stock for evaluation and qualification. Production quantities are available with 12 week lead-times, depending upon volumes.
