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

TUALATIN, Ore. — January 21, 2014 — 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.

Summary

  • Product name: PQMC3-S, PQM3-M
  • Availability: 4-6 weeks production
  • Possible users: Industrial, test & measurement, telecom, battery-driven applications
  • Primary features: Low power draw, compact footprints, wide temperature range
  • Cost: $11.42 per unit through distribution in 100 piece quantities. Contact CUI directly for OEM pricing.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
