SMT15E-12V SERIES
0.8 Vin to 3.63 Vin Single output
SMT15E Series
| 15 A DC-DC
E Class Non-Isolated DC-DC Converters
1
[ 2 YEAR WARRANTY ]
15 A Current rating
Input voltage range: 10.0 Vdc - 14.0 Vdc
Output voltage range: 0.8 Vdc - 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 SMT15E-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 SMT15E-12
offers a wide outputs trim range, which
allows maximum design flexibility and a
pathway for future upgrades.
The SMT15E-12 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-12 offers compact size and
efficiencies of up to 94%

Stresses in excess of the maximum ratings can cause permanent damage to the device. Operation of the device is not implied at these or any
other conditions in excess of those given in the specification. Exposure to absolute maximum ratings can adversely affect device reliability.
All specifications are typical at nominal input Vin = 12V, full load under any resistive load combination at 25C unless otherwise stated.
