DC/DC Converter

TSM Series 1 Watt

The TSM series are isolated DC/DC converters with 1W output power
implemented in a molded plastic package with a pin accuracy suit­able for high volume SMD-production. The devices do not require a
special reflow process but can be soldered like standard SMD-com­ponents. With their small footprint these converters are the economi­cal solution for point of use power conversion, ground loop elimina­tion, noise reduction and digital interface applications.
