Description
The 9-36V ProLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 5A of output current. These
modules operate over an extra wide range of input voltage (VIN = 9Vdc – 36Vdc) and provide a precisely regulated output voltage from
3Vdc to 18Vdc, programmable via an external resistor. Two new features added with this family of products are the ability to externally
tune the voltage control loop and a variable current limit inversely dependent on output voltage. Other features include remote
On/Off, adjustable output voltage, over current and over temperature protection. The Ruggedized version (-D) is capable of operation
up to 105°C and withstand high levels of shock and vibration. The Tunable LoopTM, allows the user to optimize the dynamic response of
the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area and AutoLimit
enables the module to deliver the max possible output power across the entire voltage range. The 9-36V ProLynx can also be used for
negative output voltage loads through the use of a specific application schematic.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only,
functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of
the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

CAUTION: This power module is not internally fused. 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 an integrated part of
sophisticated 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 8 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.

TO OSCILLOSCOPE
The 9-36V ProLynxTM module should be connected to a low acimpedance source. A highly inductive source can affect the
stability of the module. An input capacitance must be placed
directly adjacent to the input pin of the module, to minimize
input ripple voltage and ensure module stability.
