SXN15 Series
Single output
DC/DC CONVERTERS 10.8-15W High Efficiency DC/DC Converters
• High efficiency topology, 87% typical at 5V
• 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
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 to 75VDC and are available in output
voltages of 5V, 3.3V, 2.5V and 1.8V. 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 5V, 86% for the 3.3V, 85% for the 2.5V and
83% for the 1.8V 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 EN60950 and cUL1950, the SXN15 reduces compliance
costs and time to market.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
