The TMR 2WISM Series is a set of 2 Watt SMD DC/DC converters. They operate

up to 70°C environment temperature at full load or up to 80°C with a 50% load

derating. With UL 60950-1 certiﬁcation, 1’500 VDC I/O-isolation voltage, exter-

nal On/Off and short current protection they cover a wide range of application

when space is limited. The input of the converters is designed for a wide voltage

range (4:1) and minimum load is not required.
