Gaia Converter released the MGDDI-06 series dc/dc converters that target railway, transportation, airborne, and military applications. The converter series provides an input voltage range from 12 to 160 V that suits typical battery/bus voltages including 24, 28, 36, 48, 72, 96, 110, and 125 V. The device features proprietary switching techniques with efficiency as high as 90%. With two isolated outputs (for parallel, serial, or symmetrical operation) of 5, 12, 15, and 24 V, the converters can, for example, cover a wide variety of needs, such as single 5- to 48-V output, ±15-V or 2 x 24-V outputs of 3 W each.
The converter has a 0.33-in. profile with a 1 x 0.75-in. footprint, and features an operating temperature range from –40°C to 100°C and is potted for rugged environmental conditions. The units are protected with zero to full-load regulation, trim, and on/off capability, adjustable UVLO, soft start, embedded EMI filter, and overcurrent and overtemperature protection. The converters do not use optocouplers in the feedback loop. Complying with Mil-Std-704, 1275, DO-160, EN50155/55022, or an equivalent standard becomes straightforward because of the wide input voltage range and the use of fixed switching frequency with an embedded LC filter.
