The SMT15E series are non-isolated dc-dc converters packaged in
a surface-mount footprint giving designers a cost effective
solution for conversion from either a 3.3 Vdc or 5 Vdc input to
output voltages of 0.8 Vdc and 3.63 Vdc. The SMT15E offers a
range of fixed outputs (and one wide trim output unit) at an
industry leading 15 A which allows maximum design flexibility and
a pathway for future upgrades. Local voltage conversion by the
SMT15E series from existing 3.3 Vdc or 5 Vdc system voltages
eliminates the need for redesign of existing power architectures
when voltage requirements change. 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 compact size and efficiencies of up
to 96%.

Notes
1 When Vin ≥ 4.5 V, then Vout can be adjusted from 0.8 Vdc to 3.6 Vdc. When Vin < 4.5 V, then
Vout can be adjusted from 0.8 Vdc to 2.75 Vdc.
2 The SMT15E 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 SMT15E:
ConfigurationConverter Operation
Remote pin open circuit Unit is ON
Remote pin pulled low Unit is ON
Remote pin pulled high [Von/off >1.2 V] Unit is OFF
A ‘Positive 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-05S3V3-RJ.
3 Full derating curves available in both the Longform Datasheet and Application Note 136.
4 When the unit is trimmed down to 0.8 V, the efficiency is 82.5%
5 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please
contact your local sales representative for details.

The ultra-wide output voltage trim range offers major advantages to users who
select the SMT15E-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 0.8 Vdc to 3.63 Vdc. When the SMT15E-05W3V3J converter
leaves the factory the output has been adjusted to the default voltage of 3.3 V.
• When Vin ≥ 4.5 V, then Vout can be adjusted from 0.8 Vdc to 3.6 Vdc
• When Vin < 4.5 V, then Vout can be adjusted from 0.8 Vdc to 2.75 Vdc
