PRODUCT OVERVIEW
The MINMAX MBU100 series is a range of 1W DC-DC converters in a miniature SIP Package featuring I/O isolation of 1000VDC. A high efficiency allows
an operating temperature range of -40℃ to +85℃. These converters offer an economical solution for many space critical applications where a voltage has
to be isolated i.e for noise reduction, ground loop elimination, digital interfaces or for board level power distribution.

Notes
1
Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
2 These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these
modules; however they may not meet all specifications listed.
3
We recommend to protect the converter by a slow blow fuse in the input supply line.
4
Other input and output voltage may be available, please contact MINMAX.
5
Specifications are subject to change without notice.
