DC/DC Conver ter
TMA Series 1 Watt
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.
