CXE15 Datasheet, PDF (1/3 Pages) Artesyn Technologies – High Efficiency DC/DC Converters

CXE15 Series
Single output
DC-DC CONVERTERS 15 W High Efficiency DC-DC Converters
• High efficiency topology, 87% typical at 5 V
• Industry standard footprint
• Wide operating temperature, up to and exceeding 65 ˚C
(natural convection)
• 90% to 110% output trim
• No minimum load
• Overvoltage protection
• Remote ON/OFF control
• Available RoHS compliant
The CXE15 is a new high efficiency open frame isolated 15 Watt converter series
in an industry standard footprint. The CXE15 features an input voltage range of 33
Vdc to 75 Vdc and are available in output voltages of 5 V and 3.3 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 and 86% for the 3.3 V. The
CXE15 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 CXE15
reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
