Description

The 9-36V ProLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 3A of output current. These
modules operate over an extra wide range of input voltage (V
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 overtemperature protection. The Tunable Loop
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.

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.
