The HQA2W120W280V-007-M is a 120W isolated DC-DC converter in a flanged quarter-brick package, designed for MIL-COTS applications with a 9 to 40V input and 28V output. It supports conduction cooling, operates with a baseplate temperature range of -55 to 115°C due to enhanced screening, and achieves 89% efficiency. The converter includes remote sense, overcurrent, overvoltage, and overtemperature protection, and meets MIL-STD-461, MIL-STD-1275, MIL-STD-704, and RTCA/DO-160 Sec 16-18 when paired with FQA or FQB input filters. Its dimensions are 60.6 x 55.9 x 12.7 mm, and it weighs no more than 100 g. It complies with IEC/UL/CSA/EN 62368-1 and 60950-1 standards and offers 2250 Vdc isolation between input, output, and baseplate.
The DC-DC converter is a type of switching power supply that converts direct currents of buslines into direct currents that are needed for devices. TDK has a lineup of DC-DC converters under the TDK-Lambda brand for the industrial equipment market boasting high-reliability and long service life made possible with advanced circuit designing technology and high-density mounting technology. The lineup of DC-DC converters by TDK-Lambda also includes isolated and non-isolated types to meet various applications along with onboard, power module and unit types and a wide range of industry-standard sizes from brick-shaped to inch-sized.
