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.
All specifications are typical at nominal input, full load at 25C unless otherwise stated

Notes
1
At nominal input and output voltage and maximum load.
2
Output ripple can be reduced to <50mV with the addition of a 33F, 25V,
AVX-TPS (or equivalent) tantalum capacitor. Consult factory for further
information.
3
For units with optional remote ON/OFF, please add the suffix `-S' to the
model number: e.g. BXA10-48S05-S. Maximum open pin voltage 14VDC.
4
Assumes balanced loads on dual output models.
5
High impedance source/long input power cable may necessitate the
introduction of an input filter.
6
Typical 9-18VDC model start-up voltage is 9V. Maximum start-up voltage
is 9.5V (>0C) or 9.7V (<0C).
7
It is recommended that an IEC127, 250V, fast blow fuse is used rated at
4A for nominal 12V models and 2A for 48V models.
8
To achieve compliance to EN55022-A and FCC part 15 Class A, external
