The SMT15E series are non-isolated dc-dc converters packaged in
a surface-mount footprint giving designers a cost effective
solution for conversion from a 12 V source. The SMT15E has a
wide input range (10 Vdc to 14 Vdc) and offers a wide 0.8 Vdc to
3.63 Vdc output voltage range with a 15A load, which allows for
maximum design flexibility and a pathway for future upgrades.
The SMT15E is designed for applications that include distributed
power, workstations, optical network and wireless applications.
Implemented using state of the art surface-mount technology and
automated manufacturing techniques, the SMT15E offers com-
pact size and efficiencies of up to 94%.

Output Voltage Adjustment of the SMT15E-12W3V3J Series
The ultra-wide output voltage trim range offers major advantages to users who
select the SMT15E-12W3V3J. It is no longer necessary to purchase a variety of
modules in order to cover different output voltages. The output voltage can be
trimmed in a range of 0.8 Vdc to 3.63 Vdc. When the SMT15E-12W3V3J converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
Notes
1
The SMT15E features an ‘Positive Logic’ Remote ON/OFF operation. If not using the Remote ON/OFF pin,
leave the pin open (the converter will be on). The Remote ON/OFF pin is referenced to ground.
The following conditions apply for the SMT15E:
Configuration
Remote pin open circuit
Remote pin pulled low [Von/off < 0.8 V]
Remote pin pulled high [Von/off >1.6 V]
Converter Operation
Unit is ON

An ‘Negative Logic’ Remote ON/OFF version is also possible with this converter. To order please place
the suffix ‘R’ at the end of the model number, e.g. SMT15E-12W3V3-TRJ.
Full derating curves available in both the Longform Datasheet and Application Note.

TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your
local sales representative for details.
NOTICE: Some models do not support all options. Please contact your local Artesyn representative or
