SIL15E Series | 15 A DC-DC Converters
E Class Non-Isolated
SIL15E-12V SERIES
0.8V - 3.63Vin Single output
15A Current rating
Input voltage range: 10.0V - 14.0V
Output voltage range: 0.8V - 3.63V
Ultra high efficiency: 94% @ 12Vin and 3.3Vout
Extremely low internal power dissipation
Minimal thermal design concerns
Designed in reliability: MTBF of 7,042,000 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 SIL15E-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
10V to 14V input to output voltages of
0.8V to 3.63V. The SIL15E-12 offers a
wide outputs trim range, which allows
maximum design flexibility and a pathway
for future upgrades.
The SIL15E-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 SIL15E-12 offers compact size and
efficiencies of up to 94%
