Sixteenth-brick dc/dc converters deliver 50W of power

Boxborough, Mass. — SynQor has developed a family of sixteenth-brick dc/dc converters aimed at telecommunications and other low-power applications. The PowerQor Mega series, which consists of board-mountable, isolated, fixed-switching frequency dc/dc converters, are available in three configurations for maximum flexibility.

The PQ60xxxSMx converters use synchronous rectification to achieve extremely high power conversion efficiencies up to 88 percent, require no minimum load and deliver up to 50W of power with minimal derating.

The PQ60xxxSMx series is available in three configurations: open frame (SMA), open frame low profile (SML), and encased (SMC) — all with identical industry standard pin-outs. Technical advances have resulted in a cost reduction of up to 26 percent, compared with previously available sixteenth-brick power solutions, according to the company.

The PQ60xxxSMx series dc/dc converters are available in a single-output configuration, and will accept a wide range of input voltages from 35 V to 75 V. Eight module versions are offered with outputs ranging from 1.2 V to 15 V, including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V, 12 V and 15 V. Power and current levels are available ranging from 30-50 W and 3-25 A, respectively. All parts are capable of withstanding input transients up to 100 V for 100 ms. The device offers a broad operating temperature range of -40°C to +100°C, and is fully RoHS 6/6 compliant.

Other features include on/off control referenced to input side, output voltage trim, remote sense, clock synchronization, continuous short-circuit protection and input under-voltage lockout. Safety features include 2250-V input-to-output isolation, and compliance with several specifications including UL 60950-1:2003, CAN/CSA-C22.2 No. 60950-1:2003, EN60950-1:2001, Needle Flame Test (IEC 695-2-2), and IEC 61000-4-2.
