The galvanic isolation allows the Internal power dissipation 550mW device to be congured to provide an isolated Input voltage VIN, NMG05 types 7V negative rail in systems where only positive rails Input voltage VIN, NMG12 types 15V exist. The wide temperature range guarantees Input voltage VIN, NMG15 types 18V startup from 40C and full 2 watt output at 85C. Input voltage VIN, NMG24 types 28V Pin compatibility with the NMR and MER1 series ensures ease of upgradeability. OUTPUT CHARACTERISTICS Parameter Conditions Min. Typ. Max.
