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, adjustable output voltage, over current, over temperature and over voltage protection. A new feature, the Tunable TM 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: DS06-129 ver. 1.09 PDF name: NSR060A0X_ds.pdf Data Sheet Naos Raptor 60A: Non Isolated Power Modules December 6, 2010 5 – 13.8Vdc input; 0.6Vdc to 5.0Vdc Output; 60A output current Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device.

The unit will shut down if the overtemperature threshold of 135ºC is exceeded at the thermal reference point T . The red 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.

To calculate the value of the trim resistor, Rtrim for a desired output voltage, use the following equation: 1.2 Rtrim = kΩ (Vo − 0.6) Rtrim is the external resistor in kΩ Vo is the desired output voltage Table 2 provides Rtrim values required for some common output voltages. By using a ±0.1% tolerance trim resistor with a TC of ±25ppm, a set point tolerance of ±0.8% can be achieved as specified in the electrical specification. The POL Programming Tool available at www.lineagepower.com under the Design Tools section, helps determine the required trim resistor needed for a specific output voltage.

External capacitors are usually CTune added to improve output voltage transient response due to load current changes. Sensitive loads may TRIM+ also require additional output capacitance to reduce output ripple and noise. Adding external capacitance RTrim however affects the voltage control loop of the module, typically causing the loop to slow down with TRIM- sluggish response. Larger values of external capacitance could also cause the module to become unstable. Figure. 43.

Flow Through-Hole Lead-Free Soldering Information Figure 44. Thermal Test Set-up. The RoHS-compliant through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3°C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210°C. For Pb solder, the recommended pot temperature is 260°C, while the Pb-free solder pot is 270°C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process.
