The extra wide input voltage range, from 9V to 36V, makes it suitable for a wide range of applications with different bus voltages, such as 12V, 15V, 24V or 28V. The output voltage of this converter can be programmed in the range of 3V 6V. The wide input/output voltage ranges, high power density, and user-friendly features are ideal for todays industrial, telecom, datacom, wireless networks, computing, and automotive applications. This NAT converter provides competitive cost, high performance, high reliability and quality, and flexibility of use in a wide range of applications. The open frame design with integrated magnetics has a small footprint (2x0.27), achieving industry-leading power density and enhanced airflow for nearby components. As a benefit of the high efficiency and resulting superior thermal performance, these converters can provide high output currents in challenging environments with simple thermal management. This converter provides input under-voltage lockout, remote sense, wide output voltage trim, overload and short circuit protection and over-temperature shutdown as standard features. NetPower also offers several optional features to allow system designers the freedom required to optimize the system performance. The optional output over-voltage protection provides increased protection and system reliability in practical applications. The optional output voltage sequence/tracking feature allows the output voltage to track an external signal during startup and shutdown in systems with sensitive powering timing requirements. To further improve thermal performance, and provide flexibility to be used in conduction-cooled systems, the baseplate option provides necessary thermal management enhancement for the challenging environment common in many of todays electronic systems.
