PQ60xxxSMx DC/DC converter

SynQor has introduced the PQ60xxxSMx family of sixteenth-brick DC/DC converters that offer an efficient yet economical power solution.

The series is composed of next-generation, board-mountable, isolated, fixed switching frequency DC/DC converters, which are particularly useful for telecom and other low power applications. PQ60xxxSMx converters use synchronous rectification to achieve extremely high power conversion efficiencies up to 88 per cent. They require no minimum load and can deliver up to 50W of power with minimal derating.

To accommodate a broad spectrum of applications, the PQ60xxxSMx series is available in open frame SMA configuration, 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 will accept a wide range of input voltages from 35V to 75V. Eight module versions are offered with outputs ranging from 1.2V to 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 30W to 50W and from 3A to 25A, respectively. All parts are capable of withstanding input transients up to 100V for 100ms. The device has a broad operating temperature range of -40°C to +100°C, and is fully RoHS 6/6 compliant.

The PQ60xxxSMx series includes on/off control referenced to input side, output voltage trim, remote sense, clock synchronisation, continuous short-circuit protection and input under-voltage lockout. Safety features include 2,250V 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. PQ60xxxSMX DC/DC converters are value-priced starting at Rs.1,563.14 ($32) in 1,000-piece quantities.
