FEATURES Wide Temperature Performance at Full 1Watt Load, -40C to 85C Lead Frame Technology CECC00802 Reflow (280C) Dual Isolated Output 1kVDC Isolation Efficiency to 78% Power Density 1.36W/cm3 5V & 12V Input 5V, 9V, 12V and 15V Output Footprint Over Pins 1.64cm2 UL 94V-0 Package Material No Heatsink Required Internal SMD Construction Toroidal Magnetics Plastic Encapsulated MTTF up to 2.1 Million Hours Custom Solutions Available Multi Layer Ceramic Capacitors Lead Free Compatible DESCRIPTION
The NTA series of miniature surface mounted DC-DC Converters employ leadframe technology and transfer moulding techniques to bring all of the benefits of IC style packaging to hybrid circuitry. The devices are fully compatible with CECC00802 to 280C which allows them to be placed and reflowed with IC's, thus reducing time and cost in production. Co-planarity of the lead positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged.

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.

Calculated using MIL-HDBK-217F with nominal input voltage at full load. See derating curve. 12V input types have typically 3% less load regulation change. Supply voltage must be discontinued at the end of the short circuit duration. If components are required in tape and reel format suffix order code with -R, e.g. NTA0505M-R
All specifications typical at TA=25C, nominal input voltage and rated output current unless otherwise specified.
