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.
