Synqor introduces the PQ60xxxSMx converters

The PQ60xxxSMx series of DC-DC converters is composed of board-mountable, isolated, fixed switching frequency DC-DC converters that are particularly useful for telecom and other low-power applications.

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

To accommodate a broad spectrum of applications, the highly versatile PQ60xxxSMx series is available in three configurations, including 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 per cent compared with previously available sixteenth-brick power solutions.

PQ60xxxSMx series DC-DC converters are available in a single-output configuration and accept a range of input voltages from 35 to 75V.

Eight module versions are offered with outputs ranging from 1.2-15V, including 1.2, 1.5, 1.8, 2.5, 3.3, 5.0, 12 and 15V.

Power and current levels are available ranging from 30-50W and 3-25A, respectively.

All parts are capable of withstanding input transients up to 100V for 100ms.

The range has a broad operating temperature range of -40C to +100C and is fully RoHS 6/6 compliant.

The feature-rich PQ60xxxSMx series includes on/off control referenced to input side, output voltage trim, remote sense, clock synchronisation, primary- and secondary-side enable, continuous short-circuit protection, input under-voltage lockout and input over-voltage shutdown.

Safety features include 2250V input-to-output isolation and compliance with a host of 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.

Sample and production quantities are available immediately with a stock to 10-week lead-time.
