Traco 1W SMD Single/Dual Output Unregulated Isolated DC-DC Converter - TSM Series
The Traco Power TSM series is a range of isolated, 1 Watt, DC-DC converters in a molded plastic package. The pin accuracy of these DC-DC converters is suitable for automated SMD production and the devices can be soldered without any problems in a high temperature lead free process. With their high efficiency the TSM regulated converters allows an operating temperature range of -40°C to +85°C. The small footprint of the TSM DC-DC power supplies make them an economical solution for point of load power conversion, ground loop elimination, noise reduction and digital interface applications.
