The TSH series are ultra miniature, isolated 2 Watt DC/DC-converters in SMD package. The devices can be soldered without any problems in a high temperature lead
free solder process. Requiring only 1.5 cm2 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.
