Description
The SLIN-03E1Ax 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 (V
IN
= 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 over temperature protection, and output voltage
sequencing. A new feature, the Tunable Loop
TM
, 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.

Note:
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.

Notes
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 5A. 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.

Notes:
1. Some output voltages may not be possible depending on the input voltage.
2. External capacitors may require using the new Tunable Loop

feature to ensure that the module is
stable as well as getting the best transient response (See the Tunable Loop
TM
section for details).
3. Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and
