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