DC/DC Converters TSH Series, 2 Watt Features Ultra compact SMD package (SOIC-14/18) Isolated single and dual output models I/O isolation 1000 VDC High efcfi iency up to 82% Operating temperature 40C to +85C Reflow solder temperature up to 245C High accuracy of pin Co-planarity Available in tape and reel package Lead free design, RoHS compliant 3year product warranty The TSH series are ultra miniature, isolated 2 Watt DC/DC-converters in SMD pack- age. The devices can be soldered without any problems in a high temperature lead 2 free solder process. Requiring only 1.5 cm board space they offer the ideal solution in many space critical applications. These converters are the ideal solution for point of load power conversion, ground loop elimination, noise reduction and digital interface applications.
