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 3.3V or 5V input to output
voltages of 0.8V and 3.63V. The SMT15E offers a range of fixed outputs (and one wide trim
output unit) at an industry leading 15A which allows maximum design flexibility and a pathway
for future upgrades. Local voltage conversion by the SMT15E series from existing 3.3V or 5V
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%.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated SPECIFICATIONS

Notes
1When Vin ≥ 4.5V, then Vout can be adjusted from 0.8V to 3.6V. When Vin
< 4.5V, then Vout can be adjusted from 0.8V to 2.75V.
2The 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:
Configuration Converter Operation
Remote pin open circuit Unit is ON
Remote pin pulled low Unit is ON
Remote pin pulled high [Von/off >1.2V] Unit is OFF
A ‘Positive Logic’ Remote ON/OFF version is also possible with this
converter. Please consult the factory for details.

The ultra-wide output voltage trim range offers major advantages to users who
select the SMT15E-05W3V3. 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 0.8V to 3.63V. When the SMT15E-05W3V3 converter
leaves the factory the output has been adjusted to the default voltage of 3.3V
•When Vin ≥ 4.5V, then Vout can be adjusted from 0.8V to 3.6V
• When Vin < 4.5V, then Vout can be adjusted from 0.8V to 2.75V
