Murata Power Solutions’ MEJ2 series of encapsulated compact through-hole 2 Watt DC-DC Converters are designed to provide a pin-compatible upgrade path from Murata’s NMJ, MEV1 and NMV series. The MEJ2 2W devices are available with either single or dual outputs covering the nominal voltages of 3.3, 5, 9, 12 or 15 V dc. Input voltage variants accommodate 3.3, 5, 12 or 15 V dc.
In a compact SIP format, the MEJ2 series offers safety agency recognition according to UL60950 for basic/supplementary insulation for voltages up to 200 Vrms. Recognition to the medical standard IEC 60601 (3rd Ed) is pending and provides for one measure of operator protection (MOOP) to 200 Vrms. The MEJ2 series can be used in high noise environments where conventional high isolation parts with 3 kV test ratings but only functional isolation (and no guaranteed spacings) may not be adequate.
The series maintains high levels of efficiency allowing the converter to save power, reduce temperature rise and increase product reliability.
