BXA10 SERIES

Single and dual output

[ 2 YEAR WARRANTY ]

• 1 x 2 x 0.395 inch package with stand-offs

• 13.3 Watts/in3power 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 15 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, 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.

Notes

1 At nominal input and output voltage and maximum load.

2 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.

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 (>0°C) or 9.7V (<0°C).

7 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.

8 To achieve compliance to EN55022-A and FCC part 15 Class A, external

capacitors of the following values are needed:
