Gaia has announced a line of 20W DC/DC converters geared for military and airborne applications. According to the company, the dual-output MGDD-21 series devices operate over an input range of 9V to 60V and comply with MIL-STD-1725 and DO-160 transient requirements without additional front-end protection, while achieving over 90 per cent efficiency.

With two individually isolated 5V, 12V, 15V or 24V outputs for parallel, serial, or symmetrical operation, the converters can meet a variety of design needs. Total power is 20W, with a single channel being able to provide up to 17W. The converters operate over a temperature range of -55°C to 105°C and are supplied in tiny 25.4mm x 31.75mm x 7.62mm encapsulated packages capable of withstanding rugged environmental conditions.

Units in the MGDD-21 series offer such features as soft start, input undervoltage lockout, output overvoltage protection and short-circuit protection, detailed Gaia. Soft start allows current limitation and eliminates inrush current during startup. In addition, the modules permit external synchronisation and external trim adjustment of -20 per cent/10 per cent.
