The FHW500B full-brick dc/dc converter from Tyco Electronics Power Systems provides a regulated output of 12Vdc, and is designed for use in intermediate bus architectures, enabling OEMs to use downstream, non-isolated dc/dc converters to generate additional logic.

The brick converter can also be used to power multiple fans, supporting redundancy for increased fault protection.

Operating from an input voltage of 48V, the FHW500B provides a current output of up to 42A and is claimed by the company to provide 90 percent efficiency with the use of advanced synchronous rectification technology.

A parallel pin enables multiple FHW500B converters to be used in parallel to achieve higher current levels and force the load current to be shared amongst modules, enhancing system reliability.

The FHW500B has a metal base plate construction that allows heatsinks to be added, enabling the 116.8-by-61-by-12.7mm device to function from -40C to 100C.

It features input and output overvoltage protection, input undervoltage protection, thermal protection, and output over current protection, as well as remote on/off and basic insulation. The converter also has built-in filters, reducing the need for external filters.

The FHW500B series module is priced at $222 in 1,000-unit quantities.
