All specifications are typical at nominal input, full load at 25°C unless otherwise stated SPECIFICATIONS
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 12V source. The SMT05E has a
wide input range (10V to 14V) and offers a wide 0.8V to 3.63V output voltage range with a 5A
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 91%.
•5A Current rating
•Input voltage range: 10V - 14V
•Output voltage range: 0.8V - 3.63V
•Ultra high efficiency: 91% @ 12Vin and 3.3Vout
•Extremely low internal power dissipation
•Minimal thermal design concerns
•Designed in reliability: MTBF of 6,920,000 hours
per Telcordia SR-332
•Ideal solution where board space is at a premium
or tighter card pitch is required
•Industry standard surface-mount footprint

Notes
1The SMT05E features an ‘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 SMT05E:
Configuration Converter Operation
Remote pin open circuit Unit is ON
Remote pin pulled low [Von/off <0.8V] Unit is OFF
Remote pin pulled high [Von/off >1.6V] Unit is ON
An ‘Negative Logic’ Remote ON/OFF version is also possible with this
converter. To order please place the suffix ‘-R’ at the end of the model
numer, e.g. SMT05E-12W3V3-R.

The ultra-wide output voltage trim range offers major advantages to users who
select the SMT05E-12W3V3. 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 SMT05E-12W3V3 converter
leaves the factory the output has been adjusted to the default voltage of 0.8V
