The slower the rise time of the input voltage the 3 greater the maximum value of the additional external capacitance for reliable start up. 1.95W/cm nUL 94V-0 Package Material 2 INPUT CHARACTERISTICSnFootprint 0.69cm Parameter Conditions MIN TYP MAX UnitsnSingle Isolated Output Continuous operation, 3.3V input types 2.97 3.3 3.63 nIndustry Standard Pinout Voltage Range Continuous operation, 5V input types 4.5 5.0 5.5 n3.3V, 5V & 12V Input Continuous operation, 12V input types 10.8 12.0 13.2 V n3.3V, 5V, 9V, 12V and 15V Output Reflected Ripple Current 40 60 mA p-p nNo Heatsink Required nInternal SMD Construction OUTPUT CHARACTERISTICS nFully Encapsulated with Toroidal Parameter Conditions TYP MAX Units 2 Magnetics Rated Power T = –40°C to 85°C 1 W A nNo External Components Required Voltage Set Point See tolerance envelope Accuracy nMTTF up to 2.4 Million hours Line regulation High V to low V 1.0 1.2 %/% IN IN nCustom Solutions Available 10% load to rated load, 3.3V output types 10 15 nNo Electrolytic or Tantalum 10% load to rated load, 5V output types 12 15 3 Capacitors Load Regulation 10% load to rated load, 9V output types 7.5 10 % 10% load to rated load, 12V output types 6.5 9.5 10% load to rated load, 15V output types 6.0 8.5 DESCRIPTION BW=DC to 20MHz, 3.3V output types 40 80 The NKE sub-miniature series of DC-DC BW=DC to 20MHz, 5V output types 77 100 Converters is particularly suited to isolating Ripple and Noise BW=DC to 20MHz, 9V output types 43 90 mV p-p and/or converting DC power rails. A smaller BW=DC to 20MHz, 12V output types 35 65 package size, improved efficiency, lower BW=DC to 20MHz, 15V output types 32 55 output ripple and 3kVDC isolation capability through state of the art packaging and improved technology. The galvanic isolation ABSOLUTE MAXIMUM RATINGS allows the device to be configured to provide 4 Short circuit duration 1 second an isolated negative rail in systems where Internal power dissipation 530mW only positive rails exist. The wide temperature Lead temperature 1.5mm from case for 10 seconds 300°C range guarantees startup from –40°C and full Input voltage V NKE03 types 5.5V in 1 watt output at 85°C. Input voltage V NKE05 types 7V in Input voltage V NKE12 types 15V in 1 Calculated using MIL-HDBK-217F with nominal input voltage at full load. 2 See derating curve. 3 12V input types have typically 3% less load regulation change. 4 Supply voltage must be discontinued at the end of the short circuit duration.
