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%.

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 Converter Operation
Remote pin open circuit Unit is ON
Remote pin pulled low Unit is ON
Remote pin pulled high [Von/off > 2.5 V] 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.

3 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request,
please contact your local sales representative for details.

Type of Output
S = Single
W = Wide
Output Voltage
0.75 Vdc to 3.63 Vdc
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
