MINMAX MJWI40 encapsulated 40W isolated DC-DC converters

Isolated 40W DC-DC converter breaking size limits

The MINMAX MJWI40 encapsulated 40W isolated DC-DC converters are housed in a 1”x 1” package. With a power density of 93 W/in³, up to 93% efficiency and a ultra-wide 4:1 input voltage range, they are perfect for high-performance industrial applications.

With real 40-watt output capability and no line derating across the entire input range, the MJWI40 ensures full power delivery without compromise. They provide I/O isolation rated at 1500 VDC and operate reliably in extreme temperatures ranging from -40 to +85°C, all without a minimum load requirement.

 

Additional features include low no-load power consumption, comprehensive protections such as under-voltage, overload, over temperature, and short circuit, and convenient remote on/off control with output voltage trim. An optional heatsink is available to ensure optimal heat dissipation and stable performance in more demanding environments.

 

Housed in a shielded metal case with an insulated baseplate, the MJWI40 series meets UL/cUL/IEC/EN 62368-1 safety standards (UL and CE certification expected for completion by next June).
