PRODUCT OVERVIEW
The MINMAX MKW40 series is a generation of high performance DC-DC converter modules. The product offers fully 40W in an encapsulated, shielded
metal package with dimensions of just 2.0"x1.0"x0.4". All models provide wide 2:1 input voltage range and precisely regulated output voltages. Advanced
circuit topology provides a very high efficiency up to 92% which allows an operating temperature range of -40℃ to +80℃. 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.
