The TMA series are miniature, isolated 1 W DC/DC-converters in a Single-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 distribution. The use of SMD-
technology makes it possible to offer a product with high performance at low cost.
