SLDM-12D1Ax
Non-Isolated DC-DC Converter
The SLDM-12D1Ax power modules are non-isolated dc-dc
converters that can deliver up to 12 A of output current. These
modules operate over a wide range of input voltage (VIN = 3 Vdc-
14.4 Vdc) and provide a precisely regulated output voltage from 0.45
Vdc to 5.5 Vdc, programmable via an external resistor and PMBus
control.
Features include a digital interface using the PMBus protocol,
remote On/Off, adjustable output voltage, over current and over
temperature protection. The PMBus interface supports a range of
commands to both control and monitor the module.
The module also includes the Tunable LoopTM feature that 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 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.
