SXE15 Series
Single output
• 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 SXE15 is a new high efficiency open frame isolated 15 Watt converter series in
an industry standard footprint. All models in the series feature an input voltage range
of 33 Vdc to 75 Vdc and are available in output voltages of 12 V, 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 12 V and 83% for the 1.8 V version. The SXE15 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 SXE15 reduces
compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
