These modules operate over a wide range of input voltage (V = 4.5Vdc-14Vdc) and provide a precisely regulated IN output voltage from 0.59Vdc to 6Vdc, programmable via an external resistor. Features include remote On/Off, TM adjustable output voltage, over current and over voltage protection. A new feature, the Tunable Loop , allows the user to optimize the dynamic response of the converter to match the load. * UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association. ‡ VDE is a trademark of Verband Deutscher Elektrotechniker e.V. ** ISO is a registered trademark of the International Organization of Standards Document No: DS06-124 ver. 1.11 PDF name: NSR003A0X_ds.pdf Data Sheet Naos Raptor 3A: Non-isolated DC-DC Power Modules December 6, 2010 4.5 – 14Vdc input; 0.59Vdc to 6Vdc Output; 3A output current Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of a complex power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast- acting fuse with a maximum rating of 5 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.
