The galvanic isolation allows the device to be configured to provide an isolated negative rail in systems where only positive rails exist. The wide temperature range guarantees startup from –40°C and full 2 watt output at 85°C. Pin compatibility with the NMR series ensures ease of upgradeability. FEATURES RoHS compliant Efficiency from 81% Wide temperature performance at full 2 Watt load, –40°C to 85°C UL 94V-0 package material Industry standard pinout 1kVDC isolation 5V & 12V input 5V, 9V, 12V, & 15V output Internal SMD construction Fully encapsulated with toroidal magnetics No external components required MTTF up to 3.9 million hours Pin compatible with NMR series No electrolytic or tantalum capacitors 1. See Ripple & Noise characterisation method. 2. Calculated using MIL-HDBK-217F FN2 with nominal input voltage at full load. All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified. |
