◆ Isolated single and dual output models
◆ I/O isolation 1‘000 VDC
◆ High efficiency up to 82%
◆ Operating temperature –40°C to +85°C

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
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.
