The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up. ■ Efficiency to 85% ■ Power Density up to 2.01W/cm3 ■ 5V & 12V Input INPUT CHARACTERISTICS ■ 5V, 9V, 12V and 15V Output Parameter Conditions MIN TYP MAX Units ■ Footprint from 1.05cm 2 Voltage Range 5 12 33 38 5.5 13.2 Reflected Ripple Current 4.5 10.8 20 23 V ■ UL 94V-0 Package Material Continuous operation, 5V input types Continuous operation, 12V input types 5V input types 12V input types MIN TYP MAX Units 2 W 1.2 8.5 5.2 5.5 8.5 %/% 200 mV p-p ■ No Heatsink Required mA p-p ■ Internal SMD Construction ■ Toroidal Magnetics ■ Fully Encapsulated ■ No External Components Required ■ MTTF up to 2.9 Million hours ■ Custom Solutions Available ■ No Electrolytic or Tantalum Capacitors DESCRIPTION The NML Series of DC-DC Converters is particularly suited to isolating and/or converting DC power rails. 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 NME and LME ensures ease of upgradeability.
