Description
The SLIN-06F2Ax power modules are non-isolated dc-dc converters that can deliver up to 6A of output current.
These modules operate over a wide range of input voltage (VIN=2.4Vdc-5.5Vdc) and provide a precisely
regulated output voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include
remote On/Off, adjustable output voltage, over current, and over temperature protection. 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.

CAUTION: This converter is not internally fused. An input line fuse must be used in application.
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 6A. 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.
Note: Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and
temperature conditions.
