When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up. ■ UL 94V-0 Package Material ■ Reduced Footprint at 0.98cm 2 ■ Dual Output from a Single Input Rail ■ Industry Standard Pinout ■ Power Sharing on Output ■ 3.3V, 5V & 12V Input ■ 3.3V, 5V, 9V, 12V and 15V Output INPUT CHARACTERISTICS Parameter MIN TYP MAX Continuous operation, 3.3V input types 2.97 Voltage Range Continuous operation, 5V input types 4.5 Continuous operation, 12V input types 10.8 3.3V input types Reflected Ripple Current All other types Conditions 3.3 5 12 30 20 3.63 V 5.5 13.2 60 mA p-p 35 TYP MAX Units 1 W 1.2 14 15 12 8 8.5 7 60 80 75 65 60 60 %/% ■ No Heatsink Required OUTPUT CHARACTERISTICS ■ Internal SMD Construction Parameter Conditions Rated Power2 Voltage Set Point Accuracy Line regulation TA = -40°C to 120°C ■ Fully Encapsulated with Toroidal Magnetics ■ No External Components Required ■ MTTF up to 1.6 Million hours ■ No Electrolytic or Tantalum Capacitors DESCRIPTION The NKA sub-miniature series of industrial temperature range DC-DC converters are the standard building blocks for on-boar d distributed power systems. The series offers smaller package size, improved efficiency, lower output ripple and 3kVDC isolation capability through the use of state of the art packaging and technology. Ideally suited for providing dual rail supplies on primarily digital boards with the added benefit of galvanic isolation to reduce switching noise. All of the rated power may be drawn from a single pin provided the total load does not exceed 1watt. www.dc-dc.com MIN See tolerance envelope High VIN to low V IN 10% load to rated load, 0312 & 0315 10% load to rated load, 3.3V output types 10% load to rated load, 5V output types 3 Load Regulation 10% load to rated load, 9V output types 10% load to rated load, 12V output types 10% load to rated load, 15V output types BW=DC to 20MHz, 0312 & 0315 BW=DC to 20MHz, 3.3V output types BW=DC to 20MHz, 5V output types Ripple and Noise BW=DC to 20MHz, 9V output types BW=DC to 20MHz, 12V output types BW=DC to 20MHz, 15V output types 1.0 8 10 10 6.5 6 6 25 40 50 40 40 40 ABSOLUTE MAXIMUM RATINGS Short circuit duration 4 Internal power dissipation Lead temperature 1.5mm from case for 10 seconds Input voltage V IN , NKA03 types Input voltage V IN , NKA05 types Input voltage V IN , NKA12 types 1 2 3 4 Units 1 second 550mW 300°C 5.5V 7V 15V Calculated using MIL-HDBK-217F with nominal input voltage at full load.
