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 Vdc
to 18 Vdc and 18 Vdc to 75 Vdc, and is available in single and dual output versions.
Isolation of 1500 Vdc, 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 25 °C unless otherwise stated

1At nominal input and output voltage and maximum load.
2Output ripple can be reduced to <50 mV with the addition of a 33 µF,
25 V, AVX-TPS (or equivalent) tantalum capacitor. Consult factory for
further information.
3For units with optional remote ON/OFF, please add the suffix ‘-S’ to the
model number: e.g. BXA10-48S05-SJ. Maximum open pin voltage 14
Vdc.
4Assumes balanced loads on dual output models.
5High impedance source/long input power cable may necessitate the
introduction of an input filter.
6Typical 9 Vdc to 18 Vdc model start-up voltage is 9 V. Maximum start-up
voltage is 9.5 V (>0 °C) or 9.7 V (<0 °C).
7It is recommended that an IEC127, 250 V, fast blow fuse is used rated at
4 A for nominal 12 V models and 2 A for 48 V models.
8To achieve compliance to EN55022-A and FCC part 15 Class A, external
capacitors of the following values are needed:
Model C1* C2 C3
BXA10-12xxxx 10 µF film, 25 V 0.22 µF film 0.22 µF film
BXA10-48xxxx 10 µF film, 100 V 0.22 µF film 0.22 µF film
(C2, C3 voltage rating application dependent)
* Siemens P.N. B32512-J1106-J or equivalent.
9The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on
special request, please contact your local sales representative for details.
