Single and dual output
DC/DC CONVERTERS 10W DC/DC Converters
• 4:1 input voltage range
• Approved to EN60950, UL1950, CSA C22.2 No. 950
• Operating ambient temperature of -40°C to +70°C in still air
• High demonstrated reliability with conservative component deratings
• Complies with ETS 300 019-1-3/2-3
• Complies with ETS 300 132-2 input voltage and current requirements
• Fully compliant with ETS 300 386-1
• Pin compatible with NFC10 and BXA10 series
• Basic insulation system (input to output)
The CXA10 series comprising of five different models delivers single and dual output
voltages covering 3.3V, 5V, 12V, ±5V, ±12 and ±15V. The series has a wide 4:1 input voltage
range of 18 to 75VDC. The CXA10 has been designed as a competitive open-frame
alternative for the communications market. The product is supplied in the industry standard
footprint of 2.0 x 1.0 x 0.394 inches. Other product features include overvoltage protection,
short circuit protection and remote on/off. All components are placed in a fully automated
environment. Planar magnetics are used in the design to improve the reliability and reduce
the profile of the DC/DC converter. The series has full international safety approval to
EN60950 and UL1950 reducing system compliance costs, and it has a basic insulation
system from input to output making it suitable for a wide variety of applications.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
