Rated at 3W, 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 have an operating temperature range of -40° to + 85°C at 100% load.
The PQMC3-S Series is housed in an 8-pin SIP package measuring 22 x 9.5 x 12 mm and the PQM3-M series is housed in a 16 pin SMT package measuring 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 and cost from $11.42 (100).
