Fixed frequency operation at 350kHz
MTBF in excess of 7,005,000 hours (demonstrated)
Basic insulation system
The BXA30 series, comprising 9 different models, has been conceived as an
applications-specific range of DC/DC converters, specifically addressing
telecommunications, industrial electronics, test equipment, mobile telecommunications
and distributed power applications. The series offers three wide input voltage ranges, 9-
18VDC and 36-75VDC, and is available in single and dual output versions. Designed to
meet ETSI telecoms interface standards ETS300-132-2 and BTR2511, together with
internal filtering to EN55022 level A, safety approval to EN60950 and UL1950, and
isolation of 1500VDC, the 48VDC models are ideal for telecommunications applications.
The 12V models are particularly suited to industrial, mobile telecom and test equipment
applications, featuring EN61000-4-2, -3, -4, -5 and -6 immunity compliant. Other
features include low output ripple, overvoltage protection, continuous short circuit
protection, remote enable and remote sense.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated

Notes
1Nominal, at no load.
2Low line to high line.
3Full load to no-load. For duals, the value stated is for balanced loads.
4An optional internal filter is available, which will meet VDE0871 level A,
VDE0878 level A and EN55022 level A. Add the suffix ‘-F’ to the model
number, e.g. BXA30-48S12-F. See BXA15 and BXA30 Design Note 100.
5For conducted noise operation of the BXA30 to VDE0871, VDE0878 and
EN55022 level B, see BXA15 and BXA30 Design Note 100.
6For extended operating temperature, include the heatsink option, ‘-1’ in the
model number. Max. heatsink height is 12.5mm, e.g. BXA30-48S15-1
7Reverse voltage protection can be implemented by putting a slow blow
fuse on the negative input rail. Rate the fuse for 48VDC at 1.5A and 12VDC
at 6A.
8The maximum operating ambient temperature, without derating depends
on internal power dissipation and hence efficiency and cooling method.
BXA15 and BXA30 Design Note 100 provides detailed thermal calculations
and design-in details.
9Test results to-date are 1,590,000 hours @ 46˚C. The MTBF figure shown
includes a calculated acceleration factor of 4.1 based on an activation
energy of -0.55 eV.
