SynQor Introduces Independently Regulated Dual Output Quarter-bricks

Hudson, Mass – SynQor, the technology leader in DC-DC converters, has introduced a new line of dual output Quarter-brick DC-DC converters with independent regulation. The DualQor Giga series quarter-bricks can deliver 15 amps of total output current on each rail simultaneously, without a heatsink. The high-efficiency converters also feature a very low profile (8.5mm) and industry standard footprint and pin out.

The DualQor Giga series operates from a wide input voltage of 35V to 75V and offers output voltage combinations of 3.3/2.5V, 3.3/1.8V, 3.3/1.5V and 3.3/1.2V with other voltages to soon follow. Employing the established industry standard quarter-brick footprint and dual output pin out, the unit measures 1.45" x 2.3" x 0.335", (36.8 x 58.4 x 8.5mm). The quarter-brick modules are built on a single PCB with fully automated SMT construction, offering higher reliability and superior thermal performance. All modules can deliver full load current of 15A on each rail at typical ambient environments of 55oC and 200 LFM airflow.

SynQor's new dual output quarter-bricks are designed using technology perfected in their popular eighth-brick converters. The DualQor units essentially consist of two eighth-brick modules placed in the space of a quarter-brick. The simplicity of this design will allow SynQor to quickly develop any output voltage combination required by their customer base. The high component commonality inherent to this strategy will also minimize costs, increase quality/reliability and reduce lead times.

By using independent power trains and control functions for each output, the modules provide precise output voltage set points (+/-1.5%) and offer very tight regulation for each output rail (+/-1.5%) over line, load and temperature. Cross channel interference is virtually non-existent, even during load transients.

SynQor's DualQor Giga series will feature an optional second trim pin located between the primary trim pin and the output return pin. The optional trim function will allow each output voltage to be independently trimmed by +10%, providing more accurate voltage margining and custom outputs.

The DualQor converters have 2000Vdc isolation rating and carry a comprehensive set of international safety approvals, including EN60950 and UL/cUL1950. Control and protection features include on/off control, remote sense, short circuit, output OVP and thermal shutdown.
