NMXSO SERIES Isolated 5W Regulated Single and Dual Output features Industry Standard Pinout Pin Compatible with NMXU Output Regulation 0.5% 1kVDC Isolation Single or Dual Output Short Circuit Protected 2 - NMXSO SERIES Low Profile Package Efficiency to 75% Power Density 0.53W/cm3 5V & 12V input 5V, 12V and 15V Output Footprint 9.52cm2 pin connections Single Output Type (top view) UL 94V-0 Package Material 0V +V No Heatsink Required 5 3 Internal SMD Construction Toroidal Magnetics 1 Fully Encapsulated 2 GND VIN MTTF up to 1.0 Million Hours Custom Solutions Available Dual Output Type (top view) description The NMXSO series offers a regulated 5W output in a low profile industry-standard package. When upgrading to the NMXSO from 2’’ square parts, it is possible to use the additional 16.28cm2 to add additional circuitry or reduce the overall board size. The device is protected against short-term short circuits. The regulation is ideal for stabilising supply voltages which vary due to loading, eg on backplanes in distributed power systems. --V 0V +V 5 4 3 1 2 GND VIN DC-DC Converters 2-107 NMXSO SERIES Isolated 5W Regulated Single and Dual Output absolute maximum ratings over operating free air* temperature range Input voltage VIN NMX05 types . . . . . . . . . . .
