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 (V
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
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 Loop
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.

Design Considerations
Input Filtering
The 9-36V ProLynxTM module should be connected to a low
ac-impedance 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.
To minimize input voltage ripple, ceramic capacitors are
recommended at the input of the module. Figure 28 shows
the input ripple voltage for various output voltages at
maximum load current with 2x10 µF or 3x10 µF ceramic
capacitors and an input of 12V, while Fig. 29 shows the input
ripple for an input voltage of 28V.
