SXN15 Series
Single output
1 W High Efficiency DC-DC s Converter 1
High efficiency topology, 87% typical at 5 V
Wide operating temperature, up to and exceeding 70 C
(natural convection)
90% to 110% output trim
No minimum load
Overvoltage protection
Remote ON/OFF control
Available RoHS compliant
The SXN15 is a new high efficiency open frame isolated 15 Watt converter
series in an industry standard footprint. The first four models in the series
feature an input voltage range of 33 Vdc to 75 Vdc and are available in output
voltages of 5 V, 3.3 V, 2.5 V and 1.8 V. The output voltage on each model is
adjustable from 90% to 110% of the nominal value. Typical efficiencies for the
models are 87% for the 5 V, 86% for the 3.3 V, 85% for the 2.5 V and 83% for
the 1.8 V version. The SXN15 series also has a remote ON/OFF capability with
active high or active low logic. Overcurrent and overvoltage protection features
are included as standard. With full international safety approval including
TV
EN60950 and cUL1950, the SXN15 reduces compliance costs and time to
market.
