CUI Inc. 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 x 9.5 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 in. (23.86 x 13.70 x 7.50 mm).
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.
