The component lead termination of this product range is leadfree compatible, therefore the converter can be soldered in a lead-free soldering process. The devices are fully compatible with CECC00802 to 280°C which allows them to be placed and reflowed with IC’s, thus reducing time and cost in production. Coplanarity of the lead positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged. www.dc-dc.com Isolation Capacitance MTTF1 INPUT CHARACTERISTICS ■ 5V, 9V, 12V and 15V Output ■ UL 94V-0 Package Material Input Current at Rated Load Efficiency Conditions Rated Power2 Output Voltage Accuracy Line regulation TA = – 40°C to 85°C NTH0505 All other variants High VIN to low VIN 10% load to rated load, 5V output types Load Regulation3 10% load to rated load, 9V,12V & 15V 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 MIN –5.0 –5.0 mA p-p % %/% % mV p-p ABSOLUTE MAXIMUM RATINGS Short circuit duration4 Internal power dissipation Lead temperature 1.5mm from case for 10 seconds Input Voltage VIN , NTH05 types Input voltage VIN , NTH12 types 1second 550mW 300°C 7V 15V ISOLATION CHARACTERISTICS Parameter Conditions Isolation Test Voltage Resistance Flash tested for 1 second Viso=500VDC MIN TYP 1000 1 10 MIN TYP MAX Units VDC GΩ GENERAL CHARACTERISTICS Parameter Conditions Switching Frequency All 5V input types All 12V input types 1 2 3 4 5 MAX 95 90 Calculated using MIL-HDBK-217F with nominal input voltage at full load.
