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 3.3 Vdc to 5 Vdc source. The
SMT05E has a wide input range (3.0 Vdc to 5.5 Vdc) and offers a wide 0.75 Vdc to 3.63 Vdc
output voltage range with a 5 A 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 94%.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

Output Voltage Adjustment of the SMT05E-05W3V3J Series
The ultra-wide output voltage trim range offers major advantages to users who
select the SMT05E-05W3V3J. 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 0.75 Vdc to 3.63 Vdc. When the SMT05E-05W3V3J
converter leaves the factory the output has been adjusted to the default
voltage of 0.75 V.
•
When Vin ≥ 4.5 V, then Vout can be adjusted from 0.75 Vdc to 3.63 Vdc
•
When Vin < 4.5 V, then Vout can be adjusted from 0.75 Vdc to 2.75 Vdc
Notes
1
The SMT05E features a ‘Negative 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
Remote pin open circuit
Remote pin pulled low
Remote pin pulled high [Von/off > 2.5 V]
Converter Operation
Unit is ON
Unit is ON
Unit is OFF

An ‘Positive Logic’ Remote ON/OFF version is also possible with this
converter. To order please use part number SMT05E-05W3V3-RJ or
SMT05E-05W3V3-RTJ.
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 use the on-line model number search tool
