The JFCW20 series of DC/DC power converters provides 20 watts of output power in
a 1.0 x 1.0 x 0.39 inch industry standard package and footprint. This series has
single and dual output models with 4:1 ultra wide input voltage ranges of 9-36VDC
and 18-75VDC. Some features include high efficiency, ultra low quiescent current,
1600VDC I/O isolation, remote ON/OFF, and trimmable output voltage. This series is
also protected against over voltage, over current, input under voltage, and short
circuit conditions. All models are RoHS compliant and have UL60950-1, EN60950-1,
and IEC60950-1 safety approvals.
