10 A Current rating
Input voltage range: 10 Vdc to 14 Vdc
Output voltage range: 0.8 Vdc to 3.63 Vdc
Ultra high efficiency: 94% @ 12 Vin and 3.3 Vout
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
Available RoHS compliant
THE SMT10E-12 series are non-isolated
dc-dc converters packaged in a single-in-
line footprint giving designers a cost
effective solution for conversion from a
10 Vdc to 14 Vdc input to output voltages
of 0.8 Vdc to 3.63 Vdc. The SMT10E-12
offers a wide output trim range, which
allows maximum design flexibility and a
pathway for future upgrades.
The SMT10E-12 is designed for
applications that include distributed
power,workstations, optical network and
wireless applications. Implemented using
state of the artsurface mount technology
and automated manufacturing techniques,
the SMT10E-12 offers compact size and
efficiencies of up to 94%

Note 1
Thermal reference is defined as the highest temperature
measured at any one of the specified thermal reference points.
See Figure 10: Thermal reference points.
Note 2
The Remote ON/OFF pin is referenced to ground.
Note 3
The SMT10E-12 features an ‘active high’ 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 SMT10E:
Configuration Converter Operation
Remote pin open circuit Unit is ON
Remote pin pulled low [Von/off <.8V] Unit is OFF
Remote pin pulled high [Von/off >1.6V] Unit is ON
An ‘Active Low’ Remote ON/OFF version is also possible
with this converter. Please consult the factory for details.
Note 4
Thermal reference set up: Unit mounted on an edge card test
board 203mm x 190mm. Test board mounted vertically. For test
details and recommended set-up see Application Note 143.
Note 5
Max 75ºC for full load in still air.See Application Note 143 for a
detailed thermal de-rating.
CAUTION: Hazardous internal voltages and high temperatures.
Ensurethat unit is accessible only to trained personnel. The user
must provide the recommended fusing in order to comply with
safety approvals.
