SynQor Intros Tera Series DC/DC Converters

SynQor Inc. (Hudson, MA) announced two new industry-standard, half-brick-sized, isolated dc/dc converters targeted for wireless applications. The modules are part of the PowerQor™ Tera Series and are capable of delivering high output power at 26V (250W) and 18V (165W). The converter modules employ synchronous rectification and a patented topology to achieve efficiencies of 92 percent at full load.

Each converter has a 48V nominal input (35V to 75V range) and meets input-voltage transient requirements up to 100V for 100ms. The converters feature an industry-standard footprint of 2.4in x 2.3in x 0.43in and the industry-recognized pin-out configuration. The 18V output half-brick unit can deliver 165W (9.2A) in an open frame, with no heatsink package or an optional baseplated version. The 26V output module is available in a single board design with an attached baseplate, typically needed for wireless applications. The module has a height of 0.5in and can deliver 250W of power (9.6A). Open-frame versions of the 26V device are also available.

The new Tera Series converters are targeted specifically towards wireless basestation applications. The 26V base-plated module is specially designed for use in a cold-plate assembly, while also allowing through-the-board mounting of a standard or custom heatsink. Each module has a trim range of –20/+10 percent, serving the voltage needs of power amplifiers, which typically use a voltage range of 24V to 28V and consume up to 1,000W of power. The wide operating temperature range of -40°C to +100°C and an mean time between failures greater than 2.2 million hours makes the modules suitable for use in harsh environments. Additional applications include wireless transmitters and receivers, DSL line drivers, instrumentation, and internet-working devices.

The PowerQor Tera 26V half-brick converters are available immediately for production-volume shipping. The 18V units are available for sampling and will be ready for volume shipping in April 2003. The modules are priced at $97 in OEM quantities.
