PRODUCT OVERVIEW
The MINMAX MKWI40 series is the latest generation of high performance DC-DC converter modules setting a new standard concerning power density. The
product offers fully 40W 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.
Advanced circuit topology provides a very high efficiency up to 91% which allows an operating temperature range of -40°C to +80°C. Further features
include remote On/Off, trimmable output voltage, under-voltage lockout 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.
