SynQor (Hudson, MA) introduced a 40A quarter-brick-sized isolated dc/dc converter. The PowerQor Tera Series quarter-brick can deliver up to 40A of total output current at 2.5V down to 1.2V and 35A at 3.3V, without the need for an attached heatsink. The QTA model converter is the industry’s first available quarter-brick that provides 40A of output current, according to the company.
The QTA Series has a 48V nominal input (35V to 75V range) and meets input-voltage transient requirements up to 100V for 100ms. Employing the industry-standard quarter-brick footprint and pin out, the unit measures 1.45in x 2.3in, and has a low profile of only 0.43in. The module uses synchronous rectification and features a full-load efficiency of 82 percent at 1.2Vout (87 percent at half-load) and 90.5 percent at 3.3Vout (92 percent at half-load). The QTA converter also minimizes noise, offering an output voltage ripple of only 6mVrms. This series will initially be offered at 1.2Vout and 3.3Vout with other output voltages of 1.5V, 1.8V and 2.5V being released at a later date.
"Our new quarter-brick Tera Series converter really pushes the envelope for high-density modular converters", says Martin F. Schlecht, SynQor CEO. "In just a few years we have seen output currents double as customers continually demand lower voltages and higher currents in a smaller footprint. SynQor continues to meet their demands with a broad range of products that provide scalable solutions for their power conversion requirements".
Sample quantities of the 1.2Vout and 3.3Vout QTA Tera quarter-brick converters will be available in October 2001. The modules are priced at $96.00 in 1,000-unit quantities. Additional output voltages of 1.5V, 1.8V and 2.5V (all rated to 40A) will be available in first-quarter 2002.
