Redefining “Current” Limits In Power Conversion
IMT Series 200/400W Full Bricks
Description
The IMT series of high current DC/DC converters offer
current levels that are comparable to existing full-bricks.
With a wide input voltage range of 36-75V or 18~36V, they
are available with an output voltage of either 2.5, 3.3, 5 or 12
Volts. All models feature an input filter, input undervoltage
lockout, output overvoltage and overtemperature protection,
output current limiting and short circuit protection. The
unique construction with aluminum heat spreader design
achieves efficient heat transfer with no hot spots. The use of
patented Flat Matrix Transformer technology and other
patent-pending design concepts facilitate maximum power
delivered. The converters combine creative design concepts
with highly derated power devices to achieve very high
reliability, high performance and offer a low cost solution to
systems designers that are challenged to maximize power
and minimize board space.
