MKWI50 SERIES
DC/DC CONVERTER 50W, Highest Power Density
PRODUCT OVERVIEW
The MINMAX MKWI50 series is the latest generation of high performance dc-dc converter modules setting a new standard concerning power density. The
product offers fully 50W in an encapsulated, shielded metal package with dimensions of just 2.0”x1.0”x0.4”.All models provide ultra-wide 4:1 input voltage
range and precisely regulated output voltages.
A very high efficiency up to 92% which allows an operating temperature range of -40°C to +80°C is achieved by advanced circuit topology . Further features
include remote On/Off, trimmable output voltage, under-voltage shutdown as well as overload and over-temperature protection.
Typical applications for these converters are battery operated equipment, instrumentation, distributed power architectures in communication and industrial
electronics and many other space critical applications.
