DC/DC converter suits wireless networks, telecom apps

Tyco Electronics Power Systems Inc. announced the availability of the FHW500 and FHW700 series of DC/DC converters, which provide 500W and 700W, respectively, of output power in an industry standard full size brick. The products are said to suit high power RF power amplifiers, and other wireless networks and telecom applications.

The power modules are isolated DC/DC converters that operate over an input voltage range of 36 to 75Vdc and provide a single output of 28Vdc. The output is fully isolated from the input. Built-in filtering for both input and output is said to minimize the need for external filtering.

The FHW500 features a high power density of 91W/in³ and the FHW700 has a high power density of 127 W/in³. FHW500 delivers full power at a case temperature of up to 100°C whereas FHW700 delivers full power at a case temperature of 90°C.

Both power modules are rated for a wide operating temperature range of -40°C to 100°C in a full brick package of 116.8-by-61.0-by-12.7mm. Standard features include remote on/off logic, remote sense, constant switching frequency, low output ripple and noise, over-temperature protection, output over-current/voltage protection and output voltage adjustment. Auto restart protection mode after fault shutdown and unthreaded mounting holes are available as options.

The FHW series power modules can be used in applications such as simple stand-alone operations to an integrated part of power architecture.

The FHW500 is priced at $133.90 for 1,000 units and the FHW700 is priced at $147.30 for 1,000 units. Samples are available now and standard lead time is stock to 8 weeks.
