The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up. ■ Lead Frame Technology ■ Efficiency to 78% ■ Power Density 1.36W/cm3 ■ 5V & 12V Input ■ 5V, 9V, 12V and 15V Output ■ Footprint Over Pins 1.64cm2 ■ 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 280°C 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.
