The BXA10 series of DC/DC converters, comprising 9 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 86%, the BXA10 has wide input ranges of 9-18VDC,
18-36VDC, 18-75VDC and 36-75VDC, 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.

At nominal input and output voltage and maximum load.
Output ripple can be reduced to <50mV with the addition of a 33µF, 25V,
AVX-TPS (or equivalent) tantalum capacitor. Consult factory for further
information.
For units with optional remote ON/OFF, please add the suffix ‘-S’ to the
model number: e.g.
BXA10-48S12-S.
Maximum open pin voltage 14VDC.
Assumes balanced loads on dual output models.
High impedance source/long input power cable may necessitate the
introduction of an input filter.
Typical 9-18VDC model start-up voltage is 9V. Maximum start-up voltage
is 9.5V (>0°C) or 9.7V (<0°C).
It is recommended that an IEC127, 250V, fast blow fuse is used rated at
4A for nominal 12V models; 3A for nominal 24V models and 2A for 48V
models.
To achieve compliance to EN55022-A and FCC part 15 Class A, external
capacitors of the following values are needed:
