Description
The 2A DLynxTM power modules are non-isolated dc-dc converters that shall deliver up to 2A of output current.
These modules shall operate over a wide range of input voltage (V
output voltage from 0.6Vdc to 5.5Vdc, programmable via an external resistor. Features remote On/Off, adjustable
output voltage, over current and over temperature protection. The module shall also include the Tunable Loop
feature that 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.

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 4A (see Safety Considerations section) in the positive input lead. 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.
