The SLIN-30E1AL power module is non-isolated dc-dc converter that
can deliver up to 30 A of output current. This module operates over
a wide range of input voltage (VIN = 6 - 14 VDC) and provides a
precisely regulated output voltage from 0.8 VDC to 3.63 VDC,
programmable via an external resistor.
Features include remote on/off, adjustable output voltage, over
current and over temperature protection, output voltage sequencing
and paralleling with active current sharing. 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 sections of
the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

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 time-delay fuse with a maximum rating of 30A in the
ungrounded input lead. 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.
