SynQor Introduces 100 Amp Half-brick DC-DC Converters

Targeted for high current, low voltage applications

Hudson, Mass – SynQor, the technology leader in DC-DC converters, has introduced a new line of high current, high efficiency Half-brick DC-DC converters. The PowerQor Peta series can deliver up to 100 amps of output current in a single board, open frame package. The Peta series converters use synchronous rectification and SynQor's patented topology to achieve extremely high efficiency (90% for 1.5Vout at 50A, 84% at 100A).

The PowerQor Peta half-brick line includes output voltages of 1.2V (100A), 1.5V (100A) and 1.8V (80A). All units draw power from a 48V nominal input (35V to 75V) and employ the established industry standard half-brick footprint, measuring 2.4" x 2.3" x 0.45", (61 x 58.4 x 11.4mm). The optional active current sharing feature allows for parallel operation to achieve higher power levels and N+1 redundancy for hot swap applications.

The 100A Peta series extends SynQor's award-winning line of Kilo, Mega, Giga and Tera half-brick, quarter-brick and eighth-brick modules to offer the most extensive choice of high-efficiency converters from 15A-100A to suit any power application.

The high current Peta half-brick modules are ideal for telecom and datacom applications using distributed power architectures. High-end optical networking equipment such as backbone switches and Petabit routers are just some products that require higher currents at increasingly lower voltages to power today's complex electronic circuitry. SynQor is meeting these challenges by increasing efficiency and power density while eliminating the need for a heatsink.

Due to the high levels of current capacity, SynQor's 80-100A half-bricks incorporate two additional output power pins. Several manufacturers have offered various designs for pin locations on high current half-brick modules but no accepted industry standard exists. SynQor has studied this issue extensively and has developed a design in which each pin is located just outside and in-line of the established power pin locations. More importantly, SynQor uses opposite polarity for each pair of power pins. The SynQor design provides dramatically lower spreading of resistance on the customer's load board, leading to a 10 times reduction in the inductance of connection. The improvement allows the module to exhibit better transient response, lower output ripple and improved current sharing.
