The TSM series are isolated DC/DC converters with 1W output power implemented
in a molded plastic package with a pin accuracy suitable for automated SMD-
production. The devices can be soldered without any problems in a high tempera-
ture lead free solder process. With their small footprint these converters are the
economical solution for point of load power conversion, ground loop elimination,
noise reduction and digital interface applications.
