The SMT05E 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 SMT05E 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 5A load, which allows for
maximum design flexibility and a pathway for future upgrades.
The SMT05E 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 SMT05E offers
compact size and efficiencies of up to 91%.

Notes
1 The SMT05E 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 SMT05E:
Configuration Converter Operation
Remote pin open circuit Unit is ON
Remote pin pulled low [Von/off <0.8 V] Unit is OFF
Remote pin pulled high [Von/off >1.6 V] 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 numer,
e.g. SMT05E-12W3V3-RJ.
2 Full derating curves available in both the Longform Datasheet and
Application Note.
3 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special
request, please contact your local sales representative for details.
4 NOTICE: Some models do not support all options. Please contact your local
Artesyn representative or use the on-line model number search tool at

The ultra-wide output voltage trim range offers major advantages to users who
select the SMT05E-12W3V3J. It is no longer necessary to purchase a variety of
modules in order to cover ddcifferent output voltages. The output voltage can be
trimmed in a range of 0.8 Vdc to 3.63 Vdc. When the SMT05E-12W3V3J converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
