The SMT30E 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 SMT30E has a wide input
range (8 Vdc to 14 Vdc) and offers a wide 0.8 Vdc to 3.63 Vdc output voltage range with a 30 A load,
which allows for maximum design flexibility and a pathway for future upgrades. The SMT30E 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 SMT30E offers compact size and efficiencies of up to 91%.

The SMT30E features a `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 SMT30E:
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 >2.8 V]
Unit is ON
A `Negative Logic' Remote ON/OFF version is also possible with this
converter. To order please place the suffix `R' towards the end of the
model number, e.g. SMT30E-12W3V3-TRJ.

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 SMT30E-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 SMT30E-12W3V3J
converter leaves the factory the output has been adjusted to the default
voltage of 0.8 V.
