DC/DC Converter
TMA Series, 1 Watt
•
Industry standard pinout
•
Non-regulated output
•
Single and dual output models
•
I/O isolation voltage 1000VDC
•
High efficiency
•

The TMA series are miniature, isolated 1 W DC/DC-converters in a Sin-
gle-in-Line package (SIP). Requiring only 1.2 cm2 board space they offer the
ideal solution in many space critical applications for board level power distribu-
tion. The use of SMD technology makes it possible to offer a product with high
performance at low cost.
