The SLIN-03E1A power modules are non-isolated DC-DC converters
that can deliver up to 3 A of output current. These modules operate
over a wide range of input voltage (VIN = 4.5 – 14 VDC) and provide
a precisely regulated output voltage from 0.59 VDC to 5.5 VDC,
programmable via an external resistor.
Features include remote on/off, adjustable output voltage, over
current protection, over temperature protection and output voltage
sequencing. 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.

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

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