Murata 1W SIP Single and Dual Output Isolated DC-DC Converter - MEJ1 Series


The Murata Power MEJ1 is a series of isolated 1 Watt DC-DC converters, encapsulated in a 7 pin SIP package. The DC-DC converter complies with the 3rd edition of medical safety standard and provides the following MOOP (means of operator protection): 2 MOOP based upon a working voltage of 200Vrms max - 280Vpkmax, between primary and secondary and 1 MOOP based upon a working voltage of 200Vrms max, between primary and its enclosure.

Typical energy efficiencies of these DC-DC converters are in the range of 70 to 78%.

The MEJ1 series is designed for low power applications that require a high degree of isolation such as an agency-approved safety barrier for medical equipment, IGBT drivers, and control systems.
