SMT05E-12V SERIES
0.8 Vin - 3.63 Vin Single output
SMT05E Series | 5 A DC-DC Converters
E Class Non-Isolated
1
[ 2 YEAR WARRANTY ]
5 A Current rating
Input voltage range: 10.0 Vdc to 14.0 Vdc
Output voltage range: 0.8 Vdc to 3.63 Vdc
Ultra high efficiency: 91% @ 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 SMT05E-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 12
V input to output voltages of 0.8 Vdc to
3.63 Vdc. The SMT05E-12 offers a wide
output trim range, which allows maximum
design flexibility and a pathway for future
upgrades.
The SMT05E-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 SMT05E-12 offers compact size and
efficiencies of up to 91%

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.
