SXN15 SERIES
Single output
• High efficiency topology, 87% typical at 5V
• Industry standard footprint
• 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.
SPECIFICATION
All specifications are typical at nominal input, full load at 25°C unless otherwise stated

1 Measured as per recommended set-up. See Application Note 116 for
further details.
2 di/dt = 0.1A/µs, Vin = 48VDC, Tc = 25°C, load change = 0.5 lo max. to
0.75 lo max. and 0.75 lo max. to 0.5 lo max.
3 The SXN15 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
See Application Note 116 for further details.
4 Recommended input fusing is a 2A HRC 200V rated fuse.
5 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
6 Measured with external filter. See Application Note 116 for further details.
7 Start-up into resistive load.
8. Active low remote on/off is available. Standard product is active high.
Designate with the Suffix '-R' e.g. SXN15-48S05-R.
9. Operating ambient temperatures are specified at natural convection.
