These modules operate over a wide range of input voltage (V = 4.5Vdc-13.8Vdc) 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 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: DS06-127 ver. 1.11 PDF name: NSR020A0X_ds.pdf Data Sheet Naos Raptor 20A: Non Isolated Power Module: July 11, 2011 4.5 – 14Vdc input; 0.59Vdc to 6Vdc Output; 20A output current Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device.

If not using the i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE On/Off pin, leave the pin open (the module will be ON, 0850:2001-12 (EN60950-1) Licensed. except for the -49 option modules where leaving the pin For the converter output to be considered meeting the open will cause the module to remain OFF).

An input fuse for the module is recommended. Due to the wide input voltage and output voltage ranges of the MODULE module, different fuse ratings are recommended as shown in Table 1. These are suggested “maximum” fuse R1 ratings. However, for optimum circuit protection, the fuse 7.5K value should not be any larger than required in the end ON/OFF ENABLE application.

At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. The typical average output current during hiccup is 10% of Io,max. Overtemperature Protection To provide protection in a fault condition, these modules are equipped with a thermal shutdown circuit. The unit will shut down if the overtemperature threshold of 130ºC is exceeded at the thermal reference point T . The ref thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold.
