Lower-Cost 600W Full-Brick Isolated DC-DC Converters

TDK Corporation announces the introduction of the lower cost iFB series of 557W to 600W rated dc-dc converters. Packaged in the industry standard full-brick form factor, the iFB models offer high useable power and a robust design suitable for the demands of distributed power architectures. Applications include a wide variety of data communications, telecommunications, and test and measurement equipment.

The PCB mount iFB dc-dc converters have the industry standard full-brick footprint, measuring 116.84 x 60.96 x 13.21mm. The integral baseplate allows operation of the 12V model at 500W in an ambient temperature of 52 degrees C, with just 2m/s airflow. The use of an external heatsink or cold-plate will further extend the thermal performance. With efficiencies of up to 94%, internal power losses are reduced, ensuring reliable operation.

Two output voltages are available, both suitable for driving Point of Load converters. The 12V, 50A has a wide 7.2V to 13.2V adjustment range, and the 9.6V, 58A version can be set between 5.76V and 10.56V. Both models accept a 36- to 75-Vdc input and can operate in temperatures of -40 to +125 degrees C. Output trim and remote sense are provided as standard. Input-to-output and input-to-baseplate isolation is 1,500Vdc, with an output-to-baseplate isolation of 500Vdc.

Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
