• 1 x 2 x 0.395 inch package with stand-offs
• 13.3 Watts/in3 power density
• CISPR22 and EN55022 conducted emission level A
• UL, CSA and VDE approvals (48V input only)
• Continuous short circuit protection
• Optional remote ON/OFF
The BXA10 series of DC/DC converters, comprising 7 different models, is designed for
a wide range of applications including communications, industrial systems and mobile
battery powered systems. Packing up to 10 Watts of power into a 2 x 1 x 0.395 inch
package, with efficiencies as high as 85% , the BXA10 has wide input ranges of 9-18VDC
and 18-75VDC, and is available in single and dual output versions. Isolation of 1500VDC,
approval to EN60950 2nd edition, coupled with reduced conducted noise for simplified
compliance to FCC Part 15 level A and EN55022 level A, make the BXA10 ideal for
telecommunications and distributed power applications. Other features include
overvoltage protection, continuous short circuit protection with automatic recovery and
remote on/off, all of which minimize the need for external circuitry and make the BXA10 a
recommended component in distributed power systems.
