The BXA3 Series of DC/DC converters is designed to offer the optimum
cost/benefit power solution for a wide variety of applications including public
and private telecommunications, industrial systems and process and test
equipment. The series consists of 9 models with input voltages of 9-18VDC, 18-
36VDC and 36-75VDC, and offers standard output voltages of 3.3V, 5V, 12V and
15V in single and dual output configurations. Continuous short circuit protection,
overvoltage protection, 60mV output ripple and EN55022 level A conducted
noise compliance minimize design-in time, cost and eliminate the need for
external components.
All specifications are typical at nominal input, full load at 25C unless otherwise stated

An optional internal filter is available. When the filter is added, the BXA3 will
meet VDE0871-A, VDE0878-A and EN55022-A. Add the suffix `-F' to the
model number, e.g. BXA3-12S15-F.
6
Conducted noise filtering to EN55022 level B may be accomplished by
putting the following capacitors across the input pins.
12VDC
5F ceramic X7R dielectric type
24VDC
3F ceramic X7R dielectric type
48VDC
1F ceramic X7R dielectric type
7
Reverse voltage protection can be implemented by putting a fast blow fuse
on the positive input rail. Rate the fuse for 250mA at 48VDC input, 500mA
at 24VDC input and 1000mA at 12VDC input.
