PRODUCT OVERVIEW
The MINMAX MJW25 series is the latest range of a new generation of high performance dc-dc converter modules with very high power density.
The product offers fully 25W in a shielded metal package with dimensions of just 1.0”x1.0”x0.4”. All models provide wide 2:1 input range and tightly
regulated output voltage.By state-of-the-art circuit topology a very high efficiency up to 90% could be achieved allowing an operating temperature
range of -40°C to +80°C (with derating).
These converters are qualified for demanding applications in battery operated equipment,instrumentation,data communication,industrial and many other
space critical applications.
