Description
The 12V PicoTLynxTM 3A power modules are non-isolated dc-dc converters that can deliver up to 3A 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
0.59Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over
current and overtemperature protection, and output voltage sequencing (APTS versions). The Ruggedized version (-D) is capable
of operation up to 105°C and withstand high levels of shock and vibration. A new feature, 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 5A (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.
