Description
The 12V TLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 20A of output current.
These modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely regulated output
voltage from 0.69Vdc to 5.5Vdc, programmable via an external resistor. Features include frequency synchronization, remote
On/Off, adjustable output voltage, over current and temperature protection, power good and output voltage sequencing. 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.

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 20 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.

External capacitors may require using the new Tunable LoopTM feature to ensure that the module is stable as well as getting the best
transient response. See the Tunable LoopTM section for details.
