1-W converter meets UL60601-1 for medical use

The members of the MEJ1 series of isolated 1-W dc/dc converters are offered in an encapsulated seven-pin SIP package. The converters offer basic and supplementary isolation to meet the internationally recognized UL60950 standard. The series also complies with the 3rd edition of medical safety standard UL60601-1. It provides a means of operator protection based upon a working voltage of 200 Vrms max. and 280 Vpkmax.

The dc/dc converters are certified to a continuous working voltage of 200 Vrms when operating in a maximum ambient temperature of +85°C. Input to output isolation is rated at 5,200 Vdc for 1 s. The series is comprised of 38 models with single and dual output versions available. Single output models provide 3.3, 5, 9, 12, or 15 Vout with 3.3, 5, 12, 15, or 24 Vin. Dual versions provide ±5, ±12, ±9, or ±15 Vout with 5, 12, 15, or 24 Vin. Typical efficiencies range from 70 to 78%. The converters are designed for low power applications that require high isolation such as an agency-approved safety barrier for medical equipment, IGBT drivers, and control systems.
