These modules operate over a wide range of input voltage (V = 5Vdc-13.8Vdc) and provide a precisely regulated IN output voltage from 0.6dc to 5.0Vdc, programmable via an external resistor. Features include remote On/Off, TM adjustable output voltage, over current and over temperature 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: DS06-128 ver. 1.15 PDF name: NSR040A0X_ds.pdf Data Sheet Naos Raptor 40A Non Isolated Power Module: July 11, 2011 5 – 13.8Vdc input; 0.6Vdc to 5.0Vdc Output; 40A 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 30A (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.

To use the additional external capacitors in an optimal TM Cext 2x47μF 4x47μF 10x47μF 20x47μF 30x47μF manner, the Tunable Loop feature allows the loop to be tuned externally by connecting a series R-C R 75 75 39 33 30 TUNE between the SENSE and TRIM pins of the module, as C 3300pF4700pF 8.2nF 12nF 18nF TUNE shown in Fig. 44. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module to match the filter network connected to the output of the module. Recommended values of R and C are given TUNE TUNE in Tables 2 and 3. Table 2 lists recommended values of R and C in order to meet 2% output TUNE TUNE voltage deviation limits for some common output voltages in the presence of a 20A to 40A step change (50% of full load), with an input voltage of 12V. Table 3 shows the recommended values of R and C TUNE TUNE for different values of ceramic output capacitors up to 1500uF, again for an input voltage of 12V. The value of R should never be lower than the values shown TUNE in Tables 2 and 3. Please contact your Lineage Power technical representative to obtain more details of this feature as well as for guidelines on how to select the right value of external R-C to tune the module for best transient performance and stable operation for other output capacitance values.
