3 Watt Isolated DC-DC Converters Reduce Board Space and Cut Power Consumption in Industrial Applications

Press release date: January 21, 2014

PQMC3-S and PQM3-M familes increase efficiency across power curve and give improved performace at light and no loads

TUALATIN, Ore. -- CUI Inc today announced two isolated dc-dc converter families for industrial, test & measurement, and telecommunication applications.

The rugged and compact PQMC3-S and PQM3-M families increase total efficiency across the entire load curve and give improved performance at light and no loads. The converters are ideal for battery-powered applications where power draw under these conditions are a concern.

Rated at 3 W, the PQMC3-S Series is available with input ranges of 4.5~9, 9~18, 18~36, or 36~75 Vdc while the PQM3-M Series offers input ranges of 9~18, 18~36, or 36~75 Vdc.  Both families come equipped with an operating temperature range of -40° to + 85°C at 100% load, allowing the dc-dc converters to work reliably in harsh environments.

The PQMC3-S Series is housed in a compact 8 pin SIP package measuring 0.86" x 0.37" x 0.47" (22 mm x 9.5 mm x 12 mm) and the PQM3-M series is housed in a 16 pin SMT package measuring 0.94" x 0.54" x 0.30" (23.86 mm x 13.70 mm x 7.50).

Both families are available in single output voltages of 5, 12, or 15 Vdc while the SIP version PQMC3-S is also available in dual output voltages of ±5, ±12, or ±15 Vdc.  Outputs are fully regulated to within ±0.2% (typ.) for all line and load conditions.  Input to output isolation of 1,500 Vdc is provided across the range of models.

Protections include continuous short circuit and over current. The dc-dc converters meet CISPR22/EN55022 Class B standards with limited external components.

The PQMC3-S and PQM3-M Series are available now through distribution starting at $11.42 for 100 pieces.
