SynQor Releases 3 new Quarter-brick DC-DC Converters for Telecom Applications

Boxborough, Mass - SynQor continues to broaden its award-winning product line with the introduction of three new isolated DC-DC converter modules. In the PowerQor quarter-brick family, new releases include 5.0Vout and 18Vout modules designed for telecom applications. In addition, SynQor has released a new dual output quarter-brick capable of delivering independently regulated outputs at 5.0V and 3.3V for 100W of total power. With these new releases, SynQor expands its broad selection of high efficiency, open frame, industry standard DC-DC converters.

SynQors new 5.0V output quarter-brick, part of the Tera performance series, can deliver up to 30 amps (150W) at over 90% efficiency. The unit offers a wide telecom input range of 35-75V and employs the industry standard quarter-brick footprint and pin out, measuring 1.45 x 2.3 x 0.43. The module uses synchronous rectification and a fixed switching frequency, offering low noise with an output voltage ripple of only 10 mV (RMS). This release fills out the QTA series, which now includes outputs from 1.0V up to 12V, all from a 48V input.

SynQor has also released a new 18V output quarter-brick in the PowerQor Giga series. The unit operates from an input voltage range of 40-75V and can deliver 5.6A or 100W of total power with 91% efficiency and no derating at up to 55oC. The 18V QGA module is specifically designed to power line drivers for ADSL applications. The unit is available in both open frame and baseplated versions and has an operating temperature range of -40C to +100C.

SynQors new DualQor converter offers independently regulated outputs at 5.0V and 3.3V from a standard 48V input. This high-efficiency module provides 100 Watts of power in an industry standard dual quarter-brick footprint and pin out, with a very low profile of 0.34. By using independent power trains and control functions, the module provides precise output voltage set points (+/-1.0%) and offers very tight regulation for each output rail (+/-1.5%) over line, load and temperature. An optional pin allows for independent trimming of each voltage by up to +10%, providing more accurate voltage margining and custom outputs.

All of SynQors new quarter-brick products have 2000Vdc isolation rating and carry a comprehensive set of international safety approvals, including EN60950 and UL/cUL60950. Control and protection features include on/off control, voltage trim, input UVL, short circuit, output OVP, back drive protection and thermal shutdown.
