TDK Corporation announces the introduction of the lower cost iFB series of 557 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°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 75Vdc input and can operate in temperatures of -40°C to +125°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.
