DC/DC Conver ter

TMH Series 2 Watt

The TMV series are ultra miniature, isolated 2 W DC/DC-converters
in a Single-in-Line package (SIP). Requiring only 1.5 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.
