Single-in-Line Package (SIP)
DC/DC Converter
TMV-EN Series 1 Watt
2 Year Product Warranty
The TMV-EN series are dc/dc conver ters with supplementary high
I/O-isolation, to comply with safety standard IEC/EN 60950.
They are designed for applications where approved isolation is
required, i.e. information technology equipment or medical equipment. SMT-design and a special transformer technology made it
possible to build these converters in a ver y small SIP-package, requiring a minimum space on the PCB.
